The Tools/Posture Categories... window doesn't work in gnustep Monet--I
just see a blank window.
In the osx screenshot, it simply shows a list of posture names with no
additional control buttons. Is this a launchpad to other windows, and
if so to which window(s)?
I see that posture names in the diphones.mxml file include a
category-ref to their own posture name, as if each posture name defines
a singleton category (not declared in the <categories> section). Maybe
this window reflects that usage, but I don't understand what Monet
functions this window supports.
