Xfce4 Panel Menu is a plugin for the Xfce4 panel that provides a menu similar to the start menu in Windows XP. It contains an applications menu, a menu of recently opened apps, and user-defined shortcuts. It also includes a device mounter, from which it possible to mount devices listed in the fstab configuration file. The application menu and user shortcuts are stored in the same format as the Xfce4 root menu, so they can be edited with the tool that cames with the Xfce environment.
