Ok, given your explanation there I thought of a given theme I had downloaded, and sure enough it used a wharf. And all this time I thought the theme makers were just showing/hiding an ungodly ammount of shortcuts. It seems almost like a menu to me. It seems rather useful, why did they get rid of it? It could have been expanded to allow for different sizes, etc. Its like an easy way to make a bunch of shortcuts. So modules had to be written for it specifically? Why can't they allow for "hooks"?

Also, the question in my second paragraph still stands.
