​Sweet. That would cool. Cheers Thomas. I found it a couple of days ago,
and use it all the time. Prompt Toolkit is awesome.

Once you get a reference to their PT cli instance (as `ip.pt_cli`, or the
first arg to any prompt token method, or the `cli` attribute of any event)
you can access the input buffer, set up keybindings and any stuff like that
- basically, anywhere you're just playing with state and event handlers,
you're generally ok. But. There are still a lot of cool options that are in
the PT docs, that we can't access yet from IPython (as far as I tell).

​
The documented APIs for the inaccessible PT features involve passing stuff
to their `parse` method, using named args, but there's no obvious way to
attach the same stuff to a running instance. Any ideas would be
appreciated. As a concrete example, how would an IPython user add a bottom
toolbar:
