Ask HN: What kind of TUI would you use if it existed?

I don't understand the question, or maybe it's far too broad? Lots of TUIs exist.

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.

A block-based visualization of live I/O traffic, like `pagemon -a` does for process memory..
