Wave is a terminal, so you're free to use any editor you'd like, including vim, emacs or ed. We just provide another option for users who don't find vim or emacs very intuitive. I've used emacs to code for over 25 years and have no problem using the CLI or text editors (and it seems like neither do you), but there is a learning curve to teaching intro CS students or semi-technical folks how to use vim on the CLI ("type escape colon w q enter to save")
