You can add folders an rearrange the icons application launcher by editing the file /etc/xdg/menus/hildon.menu. The <Filename>'s in the Include section set the icons to display, so you can rearrange them or remove the ones you don't want. Adding more Menu sections will add folders (the one there represents the More..). Replace the OnlyUnallocated/ and All/ with a list of Filenames for the apps you want in the folder (see the files in /usr/share/applications/hildon).
