Why do you want to be out of the terminal? IMO the CLI is what makes the terminal editing experience good.
What I mean by out of the terminal is that I simply want my editing experience to have variable fonts, popups, borders for windows that aren't bound to font size, better icons, underlines, etc etc.
That is what I want, but in a super well presented manner. I'd happily pay ~200/y for that. BUT, I think this frontend would also have to have a "normal" editor built in, because I don't think people like me would pay enough to allow a dev to write this editor full time.
