Posting in the support thread because I was asked a question about modifying this mod's behavior, and thought the info might be useful to someone.

The request was for all (sub)categories with subcats to not be links, thus having no category listing pages, only product listing pages at the end of the trail. All category navigation to that point would be in the drop menu itself.
I found a very simple mod to the ul generator class that should do this, described in the Remove Subcategories Listing Page thread. Any comments are welcome.
