Well, I was going to do that, but I can't find the folder where gnome puts all the links to it's applications. ~/.gnome/apps/ only has OpenOffice.org, which doesn't even show up in the menu.
Since the Gnome menu has items such as Graphics, Programming, System Tools, etc, I've searched (using locate, the 'search for files' dialog, and simply digging around) for any files named/containing the text of those menu items... But, nothing ever comes up.
Any other ideas? :-)
