I’ve been using Linux for a over a decade, but haven’t used anything Gnomey in a while. I gave PopOS another try the other day because I needed a simple distro to put on a home PC for my partner to use. This is the most usable Gnome distro I have ever found!
I won’t be switching myself anytime soon, but I really like the way the tiles on Cosmic expand to always keep the screen full. I know KDE can tile using shortcuts, but have ant of you come across something on KDE that autoresizes the tiles like Pop does?


Cosmic runs its own window manager called
cosmic-comp, whereas Gnome uses Mutter. The tiling is baked into the Cosmic window manager, whereas you’d need to use an extension to get the same functionality on Gnome.Glad to hear you’re liking it, though! While I currently use Gnome with the PaperWM extension, Mutter is frustratingly behind on some current WM improvements (without good reason, IMO).
If you enjoy the tiling aspects, check out similar projects like Niri, as their window management shares some of the same codebase! Lots of neat projects out there, these days.
This is not about GNOME…
I intentionally did not answer their question, because I don’t know. What I addressed was their misconception that Cosmic is based upon Gnome.
