Bryan suggested some screen shots of what's working. Just a pair of very, very simple examples:
Here we can see the main function of the frontend (run code) and some of its code in the back. (Yes, I'm very used to graphical editors)
And here we can see my yakuake terminal with some useless stuff and a terminal frontend for ipython which connects to the same kernel (i.e.communicate through the same ports), this one changing the value of 'a' which has been already assigned in the IPythonQt window, so a message appears in the new widget on the right (plz don't heed the preview).
