I'd recommend everyone to try out cosmic-store (with cosmic-icons) when they get a chance. Whether you use COSMIC or not, it's fully functional with any desktop environment. It's packaged by default in Pop!_OS 22.04, available in Fedora 40 via ryanabx/cosmic-epoch, and the AUR.
Really great. But I would love that the "edit rounded corners" would not apply to the workspace number circle and to the switches, as it makes no sense.
My thing with squares, in some places or everywhere, but I is that they are not visually welcoming, in my very personal opinion of course. Curves look "safer" so to speak.
