[Enhancement]: Customization — Per-App Volume Mixer (EarTrumpet-style)

[laurentiu021]

Problem

Windows built-in volume mixer is basic and hard to access. Users want per-application volume control with output device routing.

Proposed solution

• Modern per-application volume control
• Per-app output device routing (game audio to headset, music to speakers)
• Save volume presets per profile
• Visual sliders with app icons
• Quick mute per-app
• System tray integration for quick access

Reopening: this feature is still planned and tracked. It is surfaced in-app as a work-in-progress page and was not yet implemented, so the closed-as-completed state was inaccurate.
