Looks nice. I do like tui editors, I like new editors, I like the "promise" of speed / rtc that comes with rust. I like new and interesting ways of doing things

This looks to be a hobby project, and it looks very professional and presentable, so good work! I like it!

But if you wanted to entice me to download and try it, I'd argue you have to give me something new. I would prefer more reasoning about why things are the way they are (keybinds are done because X). I'd prefer something that can be hacked upon (vim, Emacs, kak, etc all have scripts). I'd prefer something different (the entire window has physic simulation and typing too fast causes a massive loading force on the indents). Etc.

But this is your project, do what you want! well done!
