Nevermind, I was able to read the comments and the poster said “I WILL be open-sourcing the code ASAP, but I’m still working out exactly what that will look like, and I also have a few personal reasons for delaying.” So there’s not git yet for everybody else who is wondering.

I can’t watch the video, is there a link to a git somewhere?

Check both out over at https://distrosea.com/ to see which you like more. Also different DEs come with different standard apps like which text editor or terminal they use. If you do not have a preference there, it shouldn’t matter much. Also you can switch those out if one in particular isn’t to your liking.

Of course you can, why wouldn’t you? It’s Fedora Kinoite with added stuff for gaming. There is a special edition for devs in the making, in case you’re interested in keeping an eye on that: https://universal-blue.discourse.group/t/introducing-the-bazzite-developer-experience-alpha/7342/64

I doubt that would help, sadly. There is SO MUCH advice out there already, but people always think they are special and have a very rare and complicated use case.
