Silverblue and Kinoite setup


Silverblue allowed me to enable third-party repositories during setup, but how to do it in Kinoite?

In Kinoite, update notifications appear on the Desktop and are instantly visible, but in Silverblue, I have to go to the Software app to see whether apps are visible. How do we show updates in Kinoite on a Desktop?

Does btrfs provide any additional advantages, and how do you create snapshots?

Thank you in advance,
