I started this just for the lulz, but now I've got:

copy/paste/undo

multiple cursors

debuggers

syntax highlighting (even nested languages with jetbrains style comments!)

find-in-files

integrated documentation

integrated git client (roughly modeled after lazygit)

spell checking

and tons more that I can't even remember

It's pretty awesome and inspires me more than lulz. Highly successful art project if you ask me
