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?
Just to clarify: the “much smoother” is subjective and might be an oversimplification, but the “not using Gnome” part is correct.
Personally I don’t use any Gnome extensions and have much preferred Cosmic to the old Pop Shell. YMMV.
