We have minecrafts on linux. One useful-ish thing that I can think of (and currently use waidroid for) is myscript’s nebo, a handwritten note-taking app with quite good OCR. Since myscript don’t build their SDK for Linux, let alone apps, it’s somewhat the only way currently, I guess… Unless you can run wpf-s via wine somehow?
Cosmic-comp is my second favorite after hyprland so far due to their tiling being quite well thought-out. The problem is, it’s part of a DE and is somewhat cumbersome to configure as a standalone compositor (can be fixed by patching libcosmic, tho), and also it’s quite bare-bones when it comes to features.
Then there’s pinnacle which looks promising, but I haven’t yet tried to daily-drive it.
Also, maybe qtile, which has a Wayland back-end.
