You might also want to watch on helix, if PR 8675 is merged, then scheme will be the extension langauge, then we get the best of both world. Modal editing and scheme =)
There's also Lem, which has a good vim mode and is scriptable in Common Lisp (since it's built in CL) :D https://github.com/lem-project/lem/ It has: LSP support, a treeview, project-related commands, a directory mode, a POC git mode… with ncurses and SDL2 UIs.
the text rendering on the SDL2 frontend is much better than the last time I tried it, and performance is much improved. the install process used to be quite painful before but is very easy now. maybe sometime in the next 5 years i'll build enough willpower to start trying to port over all my stupid little emacs customizations. but it would be a bummer to lose tramp.
Helix is great and I have a plugin in mind and I aspire to get more acquainted with the lisp perspective (though I find emacs a bit much). It's gonna be fun.
