I'd like to know more, because I want that application menu for my app
but I haven't yet been able to figure out how to get the menu to show
up (when I add the gtkbuilder xml to my own, and then add the menu,
Gnome Shell loses the 'Quit' entry menu and just shows me a blank
menu. I can't seem to make the Bloatpad menu work for me at all).

That would be nice.

Well, there's /usr/lib64/python2.7/site-packages/gi/overrides/GLib.py
for starters.
