If you are talking about agents I feel like opencode has gotten pretty good UI/UX

If you are talking about a CLI editor, then micro has hit the nail on quality UX

https://micro-editor.github.io/

The UX where it completely breaks copy paste conventions on Linux? Other than that I agree it's gotten pretty good but this one thing drives me mad each time I use it.

I think that you can actually change the keybindings to follow the copy paste conventions that you want in micro

But personally I really love these new copy paste conventions, its the ctrl q convention which troubled me in ghostty but what I did was "ctrl > " write quit enter
