I'm using elementary os luna.
How can i add a new category to the Applications menu !?
Finally i found a way to do it.
First: create .directory file in /usr/share/desktop-directories/
and type these lines
Example /usr/share/desktop-directories/****.directory: (replace **** with the filename )
[Desktop Entry] Type=Directory Encoding=UTF-8 Name=????
(replace ???? with the new Category Name)
Then : add these lines to /etc/xdg/menus/pantheon-applications.menu
<Menu> <Name>????</Name> <Directory>****.directory</Directory> <Include> <And> <Category>????</Category> </And> </Include> </Menu>
finally : edit /usr/share/applications/ app.desktop (replace app with the application name you want to add to the new category) and type Categories=????;...;...(other categories);
since Elementary OS is based on Ubuntu, maybe Alacarte is something for you.
