Found 2 potential issue(s):

⚠️ WARNING

⚠️ sync_file_query_exists

bing-wallpaper@starcross.dev/files/bing-wallpaper@starcross.dev/applet.js:95

if (gFile.query_exists(null)) {

query_exists() is a synchronous call that can block on slow/network filesystems.
Prefer attempting the operation and handling a Gio.IOErrorEnum.NOT_FOUND error instead.

⚠️ lang_bind

bing-wallpaper@starcross.dev/files/bing-wallpaper@starcross.dev/applet.js:85

menuItem.connect('activate', Lang.bind(this, function() {

Lang.bind() is deprecated. Use arrow functions (() => {}) or Function.prototype.bind() instead.
