Comment 3 for bug 72732

This is rather disappointing, given that it also doesn't work with other applications like Emacs.

* Is there a way for me to easily get the Group name of arbitrary windows? xwininfo doesn't provide it, as far as I can tell. Even something that's accessible through a Python interpreter would be fine. I guess I could do a little ctypes-ing...

* Are there any other potential sources of information to determine which windows are from the same application, that you can think of?
