Having been working on/with the GCDialer glade-2 doesn't hold a candle to glade-3 in terms of usability. PyGTK seems light on documentation especially when it comes to Hildon/Maemo specific stuff though. It has been hair-pulling aggravting trying to track down things that, to me, seem like they should be trivial. Some of those issues have been how to set hildon input hints so that a field is numeric, phone, or non caps, how to properly use gconf through python, and gtk builder ( which was backported to PyMaemo ).

I've also switched to converting my glade to gtk builder xml which seems faster and better supported now and moving forward. The switch to gtkbuilder was rather trivial once you find some examples.
