Feature Request: Add Optional Translucent / Acrylic / Mica Window Support

Hi!
I’d love for XMCL to support an optional translucent UI mode, where the window (or specific panels) can use the system’s built-in blur/transparency effects.

What I’m requesting

• Add support for system-level translucent materials, such as:

  • Windows 11: Acrylic or Mica
  • macOS: Vibrancy

• Make this optional, so users can toggle translucency on/off in settings or config.

• Ideally allow:

  • Full-window translucency (seeing the wallpaper/apps behind XMCL)
  • Or applying the effect only to certain UI areas (e.g., sidebar, top bar)

Why

I prefer a clean, modern UI style where apps blend into the desktop, and Electron has recently added proper support for these effects. Having this as a toggle would let people who don’t want translucency keep the default solid theme.

Thanks!

Blocked until electron fix the bug.
