Desktop file attached. It passes desktop-file-validate But I have a couple questions. In upstream - Categories=GNOME;Application;Other; I've changed that to Categories=GNOME;Application;Other;X-Red-Hat-Extra;X-Fedora; Should I drop the "X-Red-Hat-Extra" ? I don't see that mentioned in the wiki. also the Extras_2fFedoraDesktopEntryGuidelines page mentions something called the vendor prefix. What is that? I did not find it described on the freedesktop.org desktop-entry-spec page.
