Checking it out now, seems very usable already!
Main issues I’m having are related to the Panel applets, like not being able to open Mullvad or Steam library from their right click menus.
But the standard things I’ve tried like streaming music, watching movies on VLC on a second monitor and playing games (admittedly easy stuff for the laptop like Slay the Spire and Into the Breach) all work with no issues so far.
Looking forward to getting into theming, etc and to see Cosmic get the additional Settings menus and be further refined 😄
Nope, installed directly on an old Dell laptop
