The two URLs I provided don't convince you that this isn't a fad? Of all the SWEs I know, every single one who previously used Eclipse, Atom, or Sublime is now using VSCode. Some of my Emacs & Vim friends have switched, too. I can't imagine what would change this trend in the next 5-10 years. Perhaps a new editor with an integrated LLM coding assistant that's FAR ahead of all competitors? Except VSCode is currently leading there, too.
Nice! Years ago I added home row chording to a simple text editor I was writing. It worked so well that I wondered why it's not common practice. You should write more about your project! :)
