(Basic Linux knowledge required)
Three steps are necessary to add new applications to the default menu:
1) choose/create an icon in /usr/share/pixmaps
Icon size should be 90x90 pixels
2) create a .desktop file in /usr/share/applications
For Quake3, you can download mine at http://members.chello.at/erich.kitzmuel ... na.desktop
The line "Icon=q3a.png" must refer to the icon created in step 1
EDIT: if you installed the right package, you already have fedora-quake3.desktop; probably you can use that.
3) edit /home/user/.config/xfce4/desktop/group-app.xml
Add a line to refer to the .desktop file created in step 2, e.g.
<app sequence="13">/usr/share/applications/quake3arena.desktop</app>
in the proper place.
To remove applications from the menu, just find their entry in /home/user/.config/xfce4/desktop/group-app.xml and remove it. Of course this doesn't remove the application itself. The original version of group-app.xml can be found at /etc/xdg/xfce4/desktop
