But why? You easily have 4k pixels, why use a tiny subset of those in a very inefficient way? We have proper hardware to make a bunch of these computations actually fast, and yet we should stuck with drawing relatively expensive text everywhere? If you only care about the UX of TUIs, that I can stand behind (though mostly as a guideline, it doesn't fit every workflow), but you can do that with a proper GUI just as we…
I'm curious: Do you have a nice set of GUI applications that come with the UX you'd expect of TUIs? (I'm not actually sure what the UX of TUIs is I love so much. Relative simplicity / focus on core features? Uff, notepad wins this one on vim. Fast startup times? I use gomuks, that takes a minute for the initial sync. No mouse? Moving around in TUI text editors with hjkl is slow. I either jump where I want to go with…
Also, Intellij is perhaps a better example. You can fully control it via only the keyboard, yet no amount of plugins would turn (neo)vim into something as capable as it is. And it makes good use of the extra pixels - human can take in much more information than a text grid.
