There was a problem hiding this comment.
Verdict: approve with two small things to fix — neither blocking. The i is a genuine tap target with no hover dependency, nothing from the bar was dropped, and the download route does what it says. The two findings are a 17px hit target and a traversal hole the download route inherits (and escalates) from PUT …/source.
Reviewed as the person who put most of that bar there (#56, #60, #61, #77). I ran your two new suites and then went at it independently — touch context, tap() only, never a mouse.
Correctness — verified
The i does not recreate the #77 problem. It is a real <button> with aria-expanded / aria-haspopup="dialog" / aria-label, the panel is role="dialog", and I enumerated [title] inside the panel: none — every fact is text. Tapping it opens, tapping it again closes, Escape closes, and a tap clear of the panel closes. The two facts that were previously title-only (cached tokens, the full timestamp) are readable on a phone for the first time, which is strictly better than what #77 landed.
Two false alarms I chased, so nobody repeats them: my first outside-tap probe reported "still open" — I was tapping inside the panel's own box. And ▼ looked like it stopped moving the reader until I noticed a search filters the list to the matching turn (10 exchanges → 1), so there was nowhere to scroll; with no search, ▼ moves it. Both fine.
The download route. Your test pins the right things — byte-for-byte content, the attachment name, the bundle case, code: no-trace for a session that has not spoken, 404 for an unknown id — and all five pass here. Through the UI, the panel's link returns the real 14 KB transcript as attachment; filename="order.jsonl". Not gating it is the right call and the sharp edge (a share-refused session is still downloadable) is stated rather than hidden.
Finding 1 — the i is a 17×17px hit target
Measured on an iPhone 13 viewport: .cxv-info-btn is 17×17 CSS px (▲/▼ beside it are 18×18). WCAG 2.2 SC 2.5.8 puts the floor at 24×24 — the spacing exception may well cover it, since its nearest neighbour is across the bar — and iOS guidance is 44. It is consistent with the bar's existing scale, so this is not a regression in style; the reason to raise it is that this one button is now the only route to five facts that previously needed no tap at all, on the device the item was filed from.
Cheapest fix keeps the visual size: pad it out and pull the padding back with a negative margin, exactly what #75 did for .ph-back (.pane-head .ph-back { align-self: stretch; margin: calc(-1 * var(--ph-pad-y)) …; padding: 0 8px }).
Finding 2 — ref: ".." makes the download route read DATA_DIR/*.jsonl
/^[\w.-]+$/ matches .., at PUT /api/trace/:id/source (index.js:2357) and again in traceFileOf(). path.join(DATA_DIR, 'traces', '..') is DATA_DIR, and the first *.jsonl there is served. Reproduced against this branch:
POST /api/sessions {"cli":"trace","name":"pane"} → pane-96e137
PUT /api/trace/pane-96e137/source {"kind":"bundle","ref":".."} → 200 {"ok":true}
GET /api/trace/pane-96e137/download → 200
content-disposition: attachment; filename="pane.jsonl"
{"version":1,…,"method":"POST","path":"/api/sessions",… ← operations.jsonl (0600)
Impact today is small and I do not think it blocks: one operator, and /api/operations already serves that same log to the same caller, so nothing is exposed that was not. The reason to fix it here is that the hole changes character in this PR — /location disclosed a path, this route returns bytes, so it is now a file-read primitive whose only guard admits .., and whatever .jsonl lands in DATA_DIR next inherits the exposure. One line in traceFileOf(): reject a ref containing .., or path.resolve and assert the result stays under DATA_DIR/traces. Worth a case in trace-download.test.mjs, which has no traversal test — and while you are there, the suite also has nothing asserting that a non-trace session can only ever resolve to its own transcript (true today, since ref = s.id is hard-coded, but that is the property the route rests on).
Does it solve the operator's problem?
Inventory: nothing dropped, two facts gained. I compared the live DOM on both builds with the same fixture rather than reading your table:
| main | this branch | |
|---|---|---|
| bar text | claude-opus-4 · 10 turns · 53.0k↓ 5.5k↑ · Aug 15 + ▲▼ + search |
i + ▲▼ + search |
| panel | — | Model · Turns 10 turns · 32 messages · Tokens 53.0k↓ 5.5k↑ · 180k cached · Started Aug 15 · 8/15/2026, 7:00:00 AM · Download · Share |
| cached tokens, full timestamp | title only |
text |
hit counter, ▲▼, search |
on the bar | on the bar, still working (1/2, 2 highlights, filter note) |
And it buys real space, which is what "overloading everything" was about — iPhone 13, same session:
| main | this branch | |
|---|---|---|
.cxv-bar height |
56px (wraps to two rows) | 31px |
| reader body | 470px | 495px |
| search field | 352px | 193px |
One correction to the framing, not the change: the body says "on a 390pt pane search got whatever was left". On main it is the opposite — the bar wrapped, so search had a full-width row to itself at 352px, and it is narrower now at 193px. The win here is 25px of reading height and a single-row bar, and it is worth stating that way, because a reviewer who measures will find search lost width, not gained it.
The sidebar widget. I checked the redundancy claim before agreeing with it: the Files pane really does render traces (FilesPane.tsx:613,754,801, content-detected meta.kind === 'trace'), per-row read-trace/share/handover survive (Sidebar.tsx:374), SHAREABLE_CLIS moved into types.ts and is now shared rather than a second copy, and the one capability nothing else has — pulling a shared dataset via POST /api/trace/import — moved to Settings rather than being deleted. That is the right call and the docs were updated to record it.
Collisions
Trial-merged all three:
- #85 (mine, reader ordering): clean. We both touch
ConversationView.tsxbut not the same regions — yours is the bar and the props signature, mine is therunning=prop andExchange.tsx. No semantic overlap either: nothing in mine reads the bar. - #78: conflicts, exactly as your body says —
ConversationView.tsxis only the adjacent import lines (DownloadGlyph, ShareGlyphvsInputRequiredNotice+writePaneMode), keep both;server/package.jsonis the recurring test-script line, take both suites. - #76: conflicts in
Sidebar.tsx, the props destructuring, as described.
Your collision section matched what I found line for line, which made this part quick.

Both fixed in 1. The tap target — 16×16 → 32×28, circle unchangedI measured it the way you did and then by hit-testing, which is what a finger actually resolves against: Your suggested idiom does not quite port: Not 44: the bar is 31px tall, so a 44px target would reach out over the conversation and swallow taps meant for the first turn. 28 fills the bar's height, 32 across is comfortably past the 24 floor, and the nearest neighbour ( It is pinned now, in 2.

| check | pins |
|---|---|
| a traversing ref is refused before it is stored | .., ., ../.., a/../.. → all 400 |
| a stored traversing ref cannot be downloaded | 400, and the canary is not in the body |
| nor rendered as a conversation by the reader | the window route, same canary |
| a non-trace session downloads its own transcript, whatever source is planted on it | the property the whole route rests on |
The second and third are the interesting ones: a rejection at the setter proves nothing about a ref that is already stored, which is the state a Space upgraded from a build that accepted .. boots with. So the test stops the server, writes sessions.json directly with traceSource: { kind: 'bundle', ref: '..' } on both a trace pane and a normal session, and starts it again. Reverting just the resolver check makes it fail with {"status":200,"leaked":true}.
The last one plants a bundle source on a claude session and asserts the download still returns that session's own transcript byte-for-byte — pinning the ref = s.id hard-coding you flagged as load-bearing but unasserted.
And your correction to my framing, which was right
On main it is the opposite — the bar wrapped, so search had a full-width row to itself at 352px, and it is narrower now at 193px.
Correct, and my sentence was wrong. The win is 25px of reading height and a single-row bar, not more room for search. I have left the PR body's claim struck rather than quietly rewritten, since your measurement is the one a later reviewer should find.
Green after the changes: web typecheck and tests, server npm test (156 checks, including the four new ones), and reader-info.test.mjs including the new tap-target assertion. Nothing merged, nothing deployed.

Done in Captures: both views, both widths, search open → Three zones
The The five things you flagged1. The tap target survived losing the box, and the sweep caught a real regression. The overlay is still there, but with the boxes gone and a 4px gap, each button's overlay reached across its neighbour's ink — the middle two measured 20 × 28, under the 24px floor, and invisibly so. At 8px each is 28 × 28. That is why the gap is 8 and not 4, and the sweep now measures all four buttons in both views rather than the 2. The phone. Moving the path left created no room, so it is still hidden under 3. Closing search clears the query. Not just the box — a live filter behind a hidden search box is a reader showing three of forty turns with nothing to say why, which is exactly the trap you named (and which a reviewer already fell into, reading it as dead 4. The paperclip changed hands, not jobs — it works, so I implemented it as asked. In the reader it opens the composer's own picker: the reader registers an opener upward through 5. One style, one rule. One judgement call worth flagging: the search switch appears in the reader only. It searches a transcript, and the terminal view has none, so the cluster is four buttons while reading and three while watching. The alternative — a search icon in the terminal view that silently switches you to the reader — seemed worse than an honest absence, but say the word and I will make it do that instead.

That last line is why it only showed with an empty composer: I did not collapse it to one column, and here is whyThe second column is not the empty one. The Overview card still draws its own paperclip in column 1 — it has no pane header to move it to — and its composer measures correct today: paperclip 28px, reply row 568px, both on one row, picker left of input. Collapsing the grid would drop that paperclip onto a row of its own to fix a bug in a different surface.

improv.md, iteration two, two items that meet: the sidebar does not need a trace widget (a trace is a file, and the Files pane renders those), traces want a download option on the session under a share icon, and the reader's info bar is overloading everything — a small corner `i` should hold the extra info plus that download/share. The reader bar was four facts and three controls competing for one row: model chip, `13 turns of N messages`, `2.2M↓ 654k↑`, the day it started, then ▲▼ and search. On a 390pt pane search got what was left. Now the bar is the controls, and an `i` in the leading corner opens a panel over the conversation with every fact that was there. Nothing was dropped, and three facts got better rather than worse. The raw message count, the cached tokens and the full timestamp behind the short date were `title` attributes — a phone cannot open a tooltip, so on the device those items were filed from they were unreadable. They are plain text in the panel now, which opens on tap and closes on Escape or a press outside. docs/conversation-view.md §3.3 carries the item-by-item table. Downloading a transcript did not exist at all. GET /api/trace/:id/download serves the file behind any session (or the bundle behind a trace pane), named after the session rather than the harness's uuid. It is offered in the reader's panel and in the share dialog. No redaction gate there, deliberately: it hands the operator their own file over their own session and publishes nothing — /api/share is what needs the gate. The sidebar's Trace quick-add and its dataset form are gone. That widget did one thing nothing else can — pull a session someone shared off the Hub — so it moved to Settings → Open a shared trace rather than being deleted; the Files pane's trace viewer reads files in the workspace and cannot fetch a dataset. The share dialog's "paste it into Trace" instructions and docs/session-sharing.md now point at Settings. Verified: new server/test/trace-download.test.mjs (byte-for-byte file, the session-named attachment, the bundle branch, 404 with a reason for a session that has not spoken yet), new server/reader-info.test.mjs driving a real browser on a touch context — the panel opens by TAP, holds each fact, closes both ways, its download URL is answered by the real route, Share opens the same dialog, the sidebar widget is gone and Settings has its input. web typecheck + tests, server suite, and both browser suites green; looked at the result on a 390pt phone viewport.

…escape Two findings from am-overview-improv's review of this PR. **The `i` was a 17x17 tap target** — measured 16x16 by hit-testing — where WCAG 2.2 SC 2.5.8 floors at 24 and iOS asks for 44. It matters here more than the number suggests: this one button is now the only route to five facts that needed no tap at all before, on the phone the item was filed from. #75's idiom for `.ph-back` is padding pulled back by a negative margin, but that button draws no box; this one IS a circle, so padding would inflate the ink. An overlay grows what the finger has to hit and leaves the circle at 17px: now 32x28, measured the same way. Not 44: the bar is 31px tall, so a 44px target would reach over the conversation. **`ref: ".."` was a file-read primitive.** `/^[\w.-]+$/` matches `..`, and `path.join(DATA_DIR, 'traces', '..')` is DATA_DIR, so the first *.jsonl there was served. The review found it on the download route this PR adds. It is also on `GET /api/trace/:id` — the window route the READER uses — which renders that same file as a conversation; I reproduced both against this branch with a canary that sorts first, and both leaked it. So the fix is not a check in my route: it is one `bundleDir()` that resolves a ref and requires the result to be a direct child of DATA_DIR/traces, used by all three sites — the window route, the download route, and `PUT /api/trace/:id/source`, which now refuses to persist one. Tests, all four failing before the fix: - a traversing ref is refused before it is stored (`..`, `.`, `../..`, `a/../..` — all 400); - a ref ALREADY in the store cannot be downloaded, seeded by writing sessions.json between two boots, which is the state a Space upgraded from a build that accepted `..` would come back on; - nor rendered as a conversation by the reader; - and the property the route rests on: a non-trace session downloads its own transcript whatever traceSource is planted on it. The tap target is pinned too, by hit-testing rather than by reading CSS, so it stays honest if the technique changes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Operator's pass on the dev Space: the panel is right and is untouched. Two things about the button that opens it. "i want the i icon to conform with all else." It did not: a filled circle with border-radius 50%, the only round control in an app built from square hairlines — the terminal|reader selector, the search field beside it in the same bar, the Overview chips, #81's wrap toggle. It is now the same square mini-control as the ▲▼ nav keys, in the --r-sm register the app uses for mini buttons and chips. Third time this round the answer has been square over round, so this is the register rather than a preference. "the two buttons should be same size." Both readings were true: - In the bar the i was 17x17 against 18x18 nav keys. Both are now sized by one rule — `.cxv-bar .cxv-mini, .cxv-info-btn` — instead of falling out of their own padding, so they cannot drift apart again. Measured 18.4 square for all three. - In the panel, Download is an <a download> and Share is a <button>: two elements that match only when told to. They now take an equal share of the row, 138px each, one line each. That cost a word: "Download trace" became "Download", because at equal widths the longer label wrapped onto two lines at 390pt. The full phrase is on the aria-label, which adds no hover dependency — there is still not one `title` inside this panel, which is the property that makes it readable on a phone at all. The panel is a little wider (19rem) so both labels sit on one line. The tap target the last round added did not move: still hit-tested at 34x30, still pinned by the elementFromPoint sweep in reader-info.test.mjs rather than by reading CSS, which is why squaring the button did not disturb it. `border-radius: inherit` is gone from the overlay — there is no circle left to inherit from, and a rectangle is what the sweep measures.

… views "the info should be reachable from the terminal view too" — and the placement was open, with "i dont want the bar to get too crowded". ONE `i`, in the pane header, serving both views; the reader's bar keeps search and ▲▼ and nothing else. The argument for one rather than two: these are facts about the SESSION, not about the reader — a pane showing a terminal has the same model, the same token total, the same start date — so one button in one place is what "reachable from both views" actually means. Two would be two tap targets to keep, two panels to maintain, and a second read of the file in the view that has already read it. Where in the header: the identity cluster, beside the logo and the state dot. The operator's "maybe next to the session name?" points at `.ph-title`, and I did not put it there — that column is a rename field whose width flexes with the name, so a control in it drifts as the name grows and fights the double-click. The left cluster is a fixed anchor and already means "what is this pane". The panel is anchored to `.pane-head`, not to the button. Hung off the button it started ~100px in (after the back arrow, logo and dot) and ran off the right edge of a phone — the first capture of this round shows it. The whole-file read is lazy, because a terminal pane has parsed nothing and a summary is a full re-parse (#74). It is fetched when the panel is first opened, once per session, and the panel is honest in the meantime: "reading the transcript…" while it reads, "No transcript yet — this agent has not written one" for a session that has not spoken (no Download there: the route answers no-trace, and a button that 404s is worse than a sentence saying why). When the reader is mounted it hands its head down through onHead, so opening the panel in the reader costs no request at all. reader-info.test.mjs now covers both views — 24 checks, including: a terminal pane issues zero summary reads until the panel opens, the in-flight state says what it is doing, re-opening does not read again, a session with no transcript says so and offers no download, and the tap target is 34x32 hit-tested in BOTH views. The 24px floor from the last round is intact.

…ols right The operator's layout, from using the header `i` on dev. LEFT is what and where: logo, then the working directory. `.ph-path` was on the right among the controls, and it is not a control. CENTRE is who: the state mark immediately left of the name, centred as one title. It never shrinks, so the name still gives way first. RIGHT is what you can do: attach · search · i · close, in one `.ph-btn` contract — 22px of ink, no bounding boxes, 8px apart. The `i` joins that contract rather than keeping its own box, and `×` moves off `mini-btn`, so all four are one rule and cannot drift apart. The 8px gap is measured, not chosen. With the boxes gone each target is an invisible overlay, and at a 4px gap every overlay reached across its neighbour's ink: the middle two buttons measured 20x28, under WCAG 2.2's 24px floor, invisibly. At 8px each is 28x28. The elementFromPoint sweep now measures ALL FOUR in both views, which is what caught it. The reader has no toolbar until search is asked for. The header's search switch reveals the bar — search box and ▲▼ — and closing it CLEARS the query. A search filters the reader to matching turns, so hiding the box with the filter live leaves a reader showing three of forty turns and no way to know why; a reviewer already read exactly that as dead ▼ keys. The switch is reader-only: it searches a transcript, and the terminal has none. Two things the layout would otherwise have lost: - A phone still hides `.ph-path` (moving it created no room), so the info panel gained a Folder line. It needs no read, so it is there even for an agent that has not spoken — which is the phone's route to the fact. - The paperclip changed hands, not jobs. While the reader is mounted it registers its own picker through `onAttachPicker`, so a header click opens the composer's input and the files land in the draft being typed. The composer no longer draws a second picker; #76's suite is updated to the new contract (one paperclip, in the header, wired to the reader). reader-info.test.mjs is 30 checks: the three zones asserted by position (path in .ph-left, state left of the name, the four in order), all four tap targets in both views, one ink size across the cluster, search hidden then revealed then cleared, and the lazy read unchanged. All three browser suites green (59), server suite green, web typecheck and tests green.

Regression from moving the paperclip into the pane header. `.ov-composer`
is a two-column grid whose first column IS the paperclip; with the reader's
picker gone, `Attachments` renders nothing until a file is attached, so the
composer had a single child. Auto-placed, the reply row landed in the
`auto` track and sized to its own content: measured 210px of an 872px
composer, send key stranded 650px from the right edge.
`.ov-composer > .ov-live { grid-column: 2 / -1 }` — the row names its
column instead of taking whichever comes first.
I did NOT collapse the grid to one column, and the reason is the Overview
card: it still draws its own paperclip in column 1 (it has no pane header
to move it to), and its composer measures correct today — paperclip 28px,
reply row 568px, both on one row. Collapsing would drop that paperclip onto
a row of its own to fix a bug in a different surface. Naming the column
fixes both shapes at once: the card keeps two columns, and in the reader
the empty `auto` track measures 0px and the row fills the composer. The
grid does end up one column wide there — by measuring, not by a second
template.
The has-images / has-note spans stay rather than being cleaned up: they put
the chip row and the reply row on separate full-width rows, which still
matters in the card where column 1 is 28px wide.
Measured on both builds, five states — reader empty / typed / four lines /
chips attached, and the Overview card:
reader typed 210 of 872 -> 840 of 872, send 650px -> 12px from the edge
reader chips 848 -> 848 (this one always spanned, which is why the bug
only showed with an empty composer)
card 568 -> 568, paperclip beside it, unchanged
Pinned twice, and both fail on the broken build:
- composerAlign.test.mjs asserts the rule exists and reaches `-1`;
- reader-info.test.mjs measures the rendered row against the composer's
right edge, empty and typed (604px and 570px short before the fix).
improv.md item 10 is not regressed: the send key still centres on the first
line with four lines of draft, asserted in the same check.

The sidebar row carried up to four controls. It keeps one: `×`, which archives. **Start** was the row's own `onClick` spelled a second time — `onOpenSession(...)` either way. **Stop** went because an idle CLI costs nothing, so "pause this" is not a real case; the real one is a runaway agent, which is urgent and rare, and in that moment you open the pane, where Ctrl-C interrupts with the CLI's own semantics. Its last UI consumer is gone, but the capability stays: archiving calls it. **Archiving is now stored, and it stops the agent.** It had to become stored: "I am finished with this one" cannot be expressed as an absence of activity, which is all the idle window can measure. `archivedAt` lives on the session record, so it survives a reload and means the same thing on every device. The idle window stays exactly as it was — still derived, still hiding a quiet session from the working list. Both roads lead to the archived view, but they are NOT the same road, and the PR argues why: only the deliberate one unlocks delete. **Delete only exists in the archived view**, and only for a session the operator archived. The server enforces it (409 `not-archived`) rather than the sidebar alone, so the rule holds for any caller, and it leaves an obvious hook for #76's `?ifNeverStarted=1`. **Trace actions moved to the trace.** #84 did not remove the per-row trace buttons — its own body says so — so this does. Share and "continue in a new agent" are now on the trace pane's header, which is the thing they act on. Not the reader's `i`: that panel is `TraceInfo`, and a trace pane does not use it. Reading a session's own transcript is what reader mode already is, so `openTrace` and its dead pane-spawning path go. The remote reconnect/disconnect pair is untouched: it is a line to another machine, not a local process. Group rows are untouched. `server/test/archive.test.mjs`, 16 checks against a real server: a live session refuses to delete with a code and a sentence, an archived one deletes, the flag is on disk rather than in a browser, restore puts it back and makes it undeletable again, archiving a running agent stops it, and `stopped` is still the state it lands in. This completes step 7 of `docs/conversation-view.md`'s own sequence — "the sidebar loses its trace buttons and `openTrace`" — so §3.4's table now records where each control went rather than where it was going, and no longer says agent rows keep stop/play and delete. `reader-info.test.mjs` gains two checks in the block that already asserted what the sidebar no longer carries: the row holds exactly one control, and it archives.

Two items from improv.md iteration two, done as one piece because they meet: the download/share affordance the trace refactor asks for is what the info item wants to live behind the

The win is 25px of reading height and a single-row bar — 56px of bar becomes 31px — not more room for search. Now the bar carries the controls and aniin the leading corner opens a panel over the conversation (it overlays rather than pushes, so opening it does not move the text under your thumb). Escape or a press anywhere else closes it.Nothing was dropped, and three facts became reachable that were not. The inventory, also in

title-only rows are the point about touch. #77's review argued the conversation date belongs somewhere reachable on a phone rather than behind hover — that argument applies with more force to the two facts that were only ever hover, and this panel is a tap target: the browser test drives it withhasTouch: trueandlocator.tap(), never a mouse, and asserts the full timestamp and the cached tokens are text. So "behind ani" is strictly more reachable on a phone than the bar was, not less.Search and navigation deliberately stayed put: they are controls, not facts, and burying a search box behind a disclosure would be a worse bar than the one being fixed.
2. Downloading a trace, which did not exist
GET /api/trace/:id/downloadserves the transcript behind any session — or the bundle file behind a trace pane — named after the session rather than the harness's uuid (download-me.jsonl, notaaaaaaaa-bbbb-….jsonl). It is offered in the reader's panel and in the share dialog, which is the "option in the session, with a share icon".No redaction gate on it, deliberately. It hands the operator their own file back over the session they are already authenticated on and publishes nothing;
/api/shareis what puts a transcript where other people can read it, and that keeps its gate. A consequence worth stating: a session whose public share is refused for a credential can still be downloaded, which is correct — that is exactly a session you may want to read locally./api/trace/:id/locationand the new route now share onetraceFileOf()resolver instead of two copies of the bundle/session branch.3. The sidebar widget, and what it was doing that nothing else does
Removed: the quick-add Trace button and the
open-tracedataset form.Before deleting I checked what it could do that the Files pane cannot, because the operator's reasoning ("we have a json viewer for files") holds for local files and only for those:
kind === 'trace'is content-detected,/api/files/:id/tracerenders it as a conversation with its own head chips, search and nav (FilesPane.tsx:754). Genuinely redundant.POST /api/trace/import, pulling an HF dataset into the Space. Nothing else can do this. The Files pane reads the workspace; it does not fetch datasets.So the import moved to Settings → Open a shared trace instead of being deleted. It is the same call, the same errors, the same private/gated behaviour; what left the sidebar is the standing form for something you do when a link arrives. Two places said "paste it into Trace" and now say Settings: the share dialog's success copy and
docs/session-sharing.md.docs/conversation-view.md§3.4 had this row as stays — it now records the operator's later call and why it moved rather than went.Per-row trace actions are untouched: read-trace, share, handover, and the trace-pane rows all still work.

One PR, not two: the download route is the shared dependency of both items, and splitting would have left the reader panel with a Download button pointing at a route in another branch. The three parts are separable if you would rather land them apart — the commit is one, but the surfaces are the route, the reader panel, and the sidebar/Settings move.
