Being able to edit the contents and positioning of launchers in an application menu gives the user the ability to better customize their desktop environment. The Xubuntu team presents a number of ways their distribution's application menu can be altered using the MenuLibre utility: "The application menus offer access to all installed applications on the system, whether it was shipped by default or installed a minute ago. While the applications are organized by category, there are situations where you want to reorganize them to your liking. Alternatively, you might want to hide a launcher completely or create a new one for your own custom script. MenuLibre is an application created for that purpose by the Xubuntu team. Let’s see how you can get started with menu editing!" The rest of the tutorial is on the Xubuntu news page.
