Is this a server-specific feature?

What do you want to be added?

Hi, I'd like to propose a Picture-in-Picture / mini-player mode for Feishin as a small, always available floating window with basic controls on the queue.

The idea is to have a minimal player in a separate window that stays on top while doing other tasks, without having to repeatedly resize the main feishin window (it could even activate when the main window is minimized).

The use cases would be:

• keep music controls visible while working in other apps
• small footprint player when the main window is too large
• lightweight "now playing" view on a second monitor

Possibly, it remembers last window size/position between sessions.
