Thanks for sharing. I've been off editor hopping for quite some time, nowadays I just use some pre-defined configuration like Doom Emacs, occasionally I try to build some environment, with AI help, from "scratch" for fun and curiosity.

I really like Emacs' flexibility + evil-mode and reactivity, recently I searched for something similar and found Lem: https://github.com/lem-project/lem, looks promising, I'll try it out and compare with Emacs when I have the chance and time.
