Picture-in-picture mode
Some high level thoughts about what a proper picture-in-picture mode would look like:
- Initiated by an explicit button in the app UI
- Separate, limited UI layout in PiP mode
- Small default size in PiP mode, but resizable
- For video players, keep aspect ratio fixed when resizing
- Above all other windows
- Independent of workspaces (does not move in overview)
Example for video player (controls visible on hover):
