[jQuery] TreeView question

[GTGeek88]

I'm looking at using the treeview plugin by Jorn.  What I'm wondering
is how to get folders added at a particular spot and how to manage
folders by dragging them around (or in some other fashion).  Perhaps
there are some plugins to the plugin, so to speak.  Or maybe there is
another one better suited to folder management.  Could anyone give
some suggestions or recommendations?  His plugin is working well for
navigation, but I need a bit more.
