Our new, not yet released Rust-based desktop environment for Pop!_OS and other Linux distros is filling out with some essential systems that cater the DE to both users and developers alike. Customization is one of our main focuses for COSMIC, and was a huge focus for us in August, too.
I haven’t used PopOS, but then COSMIC desktop really looks interesting.
I would like to see how it competes with well established DEs like GNOME, KDE & XFCE.
