For example, I’m using Debian, and I think we could learn a thing or two from Mint about how to make it “friendlier” for new users. I often see Mint recommended to new users, but rarely Debian, which has a goal to be “the universal operating system”.
I also think we could learn website design from… looks at notes …everyone else.
NixOS with YaST support would indeed be an incredibly powerful setup. It would make the whole Nix ecosystem significantly more beginner friendly and even for someone who wants to be a poweruser. It would be really nice to have config options laid out for you in a UI. Most of the time I have to have the options search, and package search websites open because there’s no easy way to get those lists within the console.
