That's very interesting, two comments:

- Automatic black box with autocomplete is a deal breaker for me. It'll drive me mad.

- I only use the mouse in the terminal if I have to (it disturbs and slows my flow!). So anything that helps me NOT using the mouse would be better. At the moment I think it's only text select/copy I use the mouse for. And resize the window. So a magic quick way to select text and copy from the keyboard would be very nice.

But I do realize I'm not the intended audience.
