I've used vi from Linux terminal sessions for more than a decade, and VS Code as a GUI editor now most times when not in a terminal session. Am I missing something not using a GUI vi editor? I came across some dude on YouTube that calls himself "The Primeagen" that swears by VIM, but I couldn't follow his use of it.
