(Sorry for the late answer)

It looks good, thanks! I think it can go in master. My only nitpick 
would be to avoid naming the output stream yio, for two reasons:
- It's only about output, not input
- tui.py is generic enough to be useful outside Yokadi, so I'd prefer to 
avoid Yokadi references in it.

What about just naming it stdout? Usage would be tui.stdout, which is 
quite similar to sys.stdout.
