Smart menus gives menus a memory.

Example First navigate to Administer >> Site building >> Menus >> Primary links. Then click away to, say, My account. As per normal Drupal behaviour this causes the Administer menu to collapse. Now click the Administer menu item a second time, and voila! Smart menus will automagically take you all the way down the menu tree to again present you with the Primary links page.

so it will be a great feature if JQuery menu supports Smart menus. ( http://drupal.org/project/smart_menus ).

love your module...
