Re: How can I modify mnu_application_menu
This might be relavant and useful info:
"The menu module installed by default is named mnu_application_menu – it is a "custom module" which includes menu ID 42. That menu is stored in database and it can be edited from Admin » Menus.
(Do not mix this with the original application_menu module. That one can be heavily customized to match style used but it can be currently done only by editing mod-application_menu.tpl file "manually")"
