Budgie for me. Coming to the source. Otherwise I'm JWM all the way on my main distros.
Plus today I finally got grun tied to "Alt-F2" so that ANY executable can be run without having to search through menus or write a .desktop file.
My favorite file manager app, vfu (version 4.19) runs great on it with its own image viewer, qvv.
Given how often I mess things up tinkering around, I appreciate Solus' stability to be able to fall back on it if... or more likely "when" I will need to.
Be well!
