+ unfold categories, articles
+ remove the first lnk from am menu, only show the second level of the active menu and on and on

As the developer wrte above this is not easy to pic up. But if you know what you are doing this is the best!
But i hope its still developed as there are no updates for i believe more than 6 Months.
