[AccessD] Access 2007 Navigation Pane

Does anyone know where the items in the navigation pane are stored? I'm
guessing that Access queries the lists of tables and forms etc., but what
about the custom items you add? And suppose that I decide to hide some
objects? Where is that information stored?

And finally, has anyone created a wizard that will convert Switchboard Items
into this new format? If not, then I will, when I figure out where this
information lives.
