Is there a good GTD Project/To-Do TUI? And yes, I know you can do this in emacs. :)
Edit: I thought of another search term after commenting and found this: https://github.com/danimelchor/todui, which I haven't played around with yet, but looks pretty close, as long as it does a good enough job pulling in the to-dos across files+folders.
When I want to implement a TUI, I just write it myself (usually by modifying my own preexisting code) rather than use an external tool. So there isn't anything I'd like to do that I can't do. But that's not really helpful to you, sorry.
