Yes, thank you. I've seen you discussing it already, and I'd love to help, but I have almost no experience even with normal fedora, and I could barely install it onto a vm to see if everything works correctly, and also, I have never even tried any atomic distros and I have no idea how they work. If you think I can help with anything, just write me a message and if I see it I'll try to help
I would be happy to help with that aspect! I've never built a Plasma theme manually but I do know a bit about immutables so we can probably figure it out.
No, I haven't, I don't have a good refactoring tool, and I haven't yet figured out what needs to be changed to make it show up as a different theme without breaking it.
