v12.2.1

First Chrome Web Store release of the capture source feature. Pending review.

Highlights since v12.1.0

Live capture source switching (new in v12.2.0)

A Capture source dropdown in the settings lets you switch between Tab capture and Microphone / system audio without restarting the visualizer window. The choice is session-only — the window always opens on Tab, so a prior Mic pick (or a "Never allow" mic decision) can never soft-lock you out.

Combined with OS audio routing (pavucontrol "Monitor of " on Linux, Stereo Mix on Windows, BlackHole/Loopback on macOS) this visualizes any app's audio — Spotify desktop, games, system sounds, anything — not just browser tabs. See the readme for routing steps.

Reliability fixes

• Capture restart race fixed — rapidly toggling between Tab and Mic no longer leaves the visualizer in a stale state.
• Mic-denial recovery — denying the mic prompt now auto-restores Tab capture and the dropdown drops back visibly.
• Random Butterchurn preset fix — off-by-one bug that occasionally returned no preset is fixed.
• Stale-scene recovery — selecting a removed/renamed scene (built-in or custom) now falls back gracefully instead of breaking the renderer.
• Custom preset validation — corrupt or partial customPresets in storage no longer crash the settings UI.
• Smaller permission footprint — the storage manifest permission added in v12.2.0 was removed in v12.2.1 once the background service worker became the single source of truth for the active capture source.
