A text editor as UI: implementation

Editing a file as UI is a really interesting idea. Thanks for sharing. I think things like oil.nvim are an interesting extension of this - it exposes an editing interface over an ephemeral text, then interprets the edits on save to generate things like file management commands (moves, renames, etc...).

It's really powerful for some things, since you get to use the full expressiveness of the modal editor. I always struggle with some others. Like moving a non-contiguous set of files into a different directory...
