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 love the full overview as well. On every Pop installation I restore it to super key only. The Launcher then goes to it’s original keys of super + /. You end up with the full activity view with the exception of the Gnome search bar. And we’re talking about the COSMIC extension on Gnome right now, but the COSMIC desktop environment will be much more configurable from what I’ve been led to believe.
