The only question is how the separate categories should be handled in terms of the UI.

I think the easiest solution for you here is the best, I think a dropdown menu would work. For users, I guess, the most important thing is to have a way to categorize them to get straight to the needed tool/preset. Also, a dropdown menu will help to keep the UI consistent and compact, without having the Favorites window enlarging in size when adding more and more favorites....
