At the risk of cliche, I'm gonna go ahead and say that the best desktop just got a little bit better.
I've got an oled display, does it have HDR? Gnome has a handful of extensions that I love, is Cosmic extensible?
I believe HDR is planned for post release.
Cosmic is not extensible afaik in the same way as Gnome is. No idea if it's even planned.
COSMIC is the one thing making me hold out on installing hyprland at the moment :3
Yeah, I also gravitated from using traditional tiling WMs to Cosmic. I find that it's tiling is finally (in comparison to other desktop systems) good enough that I don't need those things anymore.
