I've spent a lot of time messing with terminal UIs, and I feel that the experience could be improved hugely just by adding a couple new escape sequences, for right aligned text and for filling to the rest of the width of the terminal with a character. Thanks to terminfo this shouldn't affect backwards compatibility.

I certainly don't think a full rewrite is necessary (we managed to tack on mouse support and even image rendering[0] no problem). Curses is a pain to work with directly, but this is not the fault of terminals or shells. It's really easy to create curses interfaces with libraries like blessings[1].
