[macOS] Desktop Mini Player or Widget

It would be very useful for the desktop app to include a mini player or desktop widget that allows quick access to playback controls and currently playing information.

Ideally, this could provide:

• A compact view showing the current track, artist, and artwork

• Quick controls (play/pause, next, previous)

• Optional features such as displaying lyrics (similar to the mini player experience in iTunes)

This would allow users to monitor and control playback without needing to keep the full app window open or in focus, improving multitasking and overall usability on desktop platforms.
