Large commit that totally refactor of the way we handle the bar and
panels.
Testing should focus on Panels, Bar, Keyboard Focus, IPC calls.
Changes brief:
- One NFullScreenWindow per screen which handle it's bar and dedicated
panels.
- Added shadows
- Reintroduced dimming
- New panels animations
- Proper Z ordering
- Panels on overlay laywer is not reimplemented, if we do it then the
bar will be on the Overlay too
- Panel dragging was not reimplemented, to be discussed before
reimplementing
- Still a WIP, need to work more on shadows and polishing + debugging.
Adds a visual indicator to the "Add Widget" dropdown in the Bar
settings panel to show which widgets are already in use and where.
- A small text badge ("L", "C", "R") now appears next to any widget
that is already on a panel.
- The badges are reactive and update automatically when widgets are
added or removed.
- This helps prevent accidental duplicate additions and makes widget
management easier.
- Keep bar as overlay while auto-hide is enabled (WlrLayershell.exclusionMode: Ignore) to avoid compositor relayouts and work-area changes.
- Add 1px edge "peek" PanelWindow overlay to reveal on hover;
- Animate bar with directional slide.
