I like this idea but in any way would it effect someone wanting to manually edit the template say to include a complex dropdown? I don't have enough experience to derive an answer with what I've learned so far but i tend to think no. If it doesn't effect it +1 all dayI would like to see an Admin Option to Add Tabs and Menus, much like adding forums. Then you can assign an order to them. Example:
Settings -> Add Menu
Parent: (leave blank to assign as a Tab)
+1You could also have infinitely nested menus if you wanted too. First level is tabs. Second level is sub-tab links. Additional levels open as menus.
