I miss Unity, nowadays using XFCE.
I'm still convinced every desktop environment should be a physics simulator - 2D or 3D. If you want consistent animations, changes of state, etc. you don't hardcode these into your application. Your application should exist in a physics simulator. Your windows are objects with layers. You're looking at a composited view of them. In 2023 we have the hardware and the know-how to run physics simulators as your desktop environments.

Also, as you can see on my comments history, most of my GNU/Linux use is on VMs and servers, since VMWare got good enough I have stopped the dual boot dance.
