I would like to see the choice <current tab> at the top of the list of Parent Tab.
There are 2 reasons this is needed:
1) When you are on a page which is an invisible tab (not included in menu) it will not show anything because you cannot select the current page.
2) I want to use this module as a sub-menu for every page. So I want to set it as "Display Module on All Pages"; however, when I do that now, it shows the sub-menus for the orignal page instead of the current page.
Other than this one change I would like to say that this module is awesome. I love the way I can make it a horizontal menu by setting the number of columns.
