Thanks. I know, there's a lot to improve and I'm not entirely at home in Emacs.

As a Distel-related question, it would be good if you (the Distel developers)
would set up some guidelines for extending the functionality. I put the stuff
somewhere where it was easy to make it work, but it might be better if the
distel framework was cleanly separated from the extensions.
