What it is: Crystal Dock is a cool dock (desktop panel) for Linux desktop, with the focus on attractive user interface, being simple and easy to use, and cross-desktop support.
The current version (version 2.x) supports KDE Plasma 6 on Wayland. Other desktop environments will be considered when they run on Wayland and provide sufficient APIs.
Change log:
New features:
New 3D style: reminiscence of Sun's Project Looking Glass and Apple's Mac OS X Leopard/Lion. This feature comes as default but can be turned on/off from the dock's context menu. Also this only applies to a dock in bottom position of the screen, for aesthetic reasons.
Bugs fixed:
Fixed a bug where task indicator does not change from 'active' to 'inactive' if the new active window is the dock itself.
I'd be curious to see a blog post in the future mentioning the challenges you might have faced making the dock work on Wayland, and what was needed for that.
