[Feature Request]: Open in EDITOR

[milafrerichs]

Hey Maria,

thanks for this fork and TUI implementation. I was not sure if I would use t3code but when I saw your t1code I wanted to try it out.
Are you planning on adding new features and keeping parity with t3code?

One thing I would love to see is to edit files in the default EDITOR (neovim for me). or open the folder directly in the terminal.

Thanks a ton, love playing around with it the last few days.

Keep it up.
