This is awesome. I wonder if any of this was Emacs inspired. A very common UX in Emacs is to list things in a buffer and directly manipulate the items to execute commands. For example, in dir-mode, you can select multiple files and rename them, or mark several files for deletion and execute it.

It really is a fantastic way to bring an interactive interface into a text-based world. This looks like a cool way to bring it to the terminal.
