[Feature]: Add keyboard media key support (play/pause, next, previous) to the mini-player window

[prince-pokharna]

Summary

The YTM Mini Mode extension pops YouTube Music out into a dedicated mini-player window. However, when the mini-player window is in focus, media keys on the keyboard (Play/Pause, Next Track, Previous Track) do not control YouTube Music playback. This is a significant UX gap — a mini-player that does not respond to hardware media keys defeats a primary use case of the extension: controlling music without switching context.

Problem

• Media key events (MediaPlayPause, MediaTrackNext, MediaTrackPrevious) dispatched at the OS level are only handled by the active/focused tab in the main browser window.
• When the mini-player window (the popped-out picture-in-picture-style window) has focus, media keys have no effect on YouTube Music playback.
• Users who use hardware keyboards with media keys or headphone/headset controls expect these to work regardless of which window is focused.
• This is a commonly reported friction point in browser extensions that implement pop-out players.

Impact

• Users must switch back to the main YouTube Music tab to use media keys, directly undermining the extension's purpose.
• Headphone users who rely on inline media controls cannot use them while the mini-player is their active window.

Proposed Solution

I would like to implement media key forwarding using the Web Extensions API within the content script or background service worker:

1. In the mini-player window: Listen for keydown events matching MediaPlayPause, MediaTrackNext, MediaTrackPrevious.
2. Message passing: Use chrome.runtime.sendMessage / browser.runtime.sendMessage to forward the key event to the background script.
3. In the background script: Use chrome.tabs.sendMessage to relay the command to the main YouTube Music tab's content script.
4. In the content script (YTM tab): Dispatch a synthetic click on the relevant YTM player button (yt-icon-button[aria-label="Play pause"], next/previous buttons).

This approach works entirely within the existing message-passing architecture the extension already uses, requires no new permissions, and is fully compatible with both Manifest V2 (Firefox) and Manifest V3 (Chrome).

I am happy to implement and test this across both browsers. Could you please assign this issue to me?
