Show levels and drop down feature

At first I would like to say thanks for this great plugin.
Could you add two features.
1st > ” How many level will show ” . I mean something like ( only top cat., 1 child, 2 child , 3 child etc… )

2sec ” Drop down ” .If I chose to show only 2 deep level category ( top category ant 1 child cat for this top cat. ). Top categories will not drop down but only child cat ( and if I drop down one of child cat, and then I drop down next child cat the first one child cat will roll up ).

If you could add this two functionality that will be Awesome !

Apologize for my english ??
