Is there any way to remove the "Favorites" and "Recently Used" categories in the Whisker menu (Xubuntu 14.04)? Neither the Whisker menu nor Menulibre allow me to do that. I did a bit of research, but I couldn't find the right configuration file.

Is there anyone out there who could help me out?
You can test this out (I haven't):

Edit the file ~/.config/xfce4/panel/whiskermenu-29.rc and comment out the lines beginning favorites= and recent= and see what effect that has. You may have to log out and back in.
