Also been thinking this.

What I want from a text editor is:

- Like you said, running tasks with a button/keybind, easily customizable (Like I wanna open a config file, add a function/script, bind to key/create UI button, done, not make a "plugin" not compile an "extension" or anything like that)

- Fuzzy finding/search - ripgrep and fzf can do that, so just bundle those I guess, or write my implementation of those.

- Must start instantly, load files instantly, every action needs to takes at most 100 ms.

- Be a "portable application", i.e it sits in a folder with everything it needs and I can copy that folder to any computer and be up and running with exactly the same configuration.

and NOTHING else.
