OK Steve, I understand and agree with you. A sub-site is just an instance of the sub-site package. But (I contend) in the user-view it is a different type of package in the sense that it can "contain things".
Obviously programmers like to make hierarchies, and maybe it is not a good idea to make another one, but I am thinking that to the user all of these applications are not "equal". I guess I was thinking that lack of a "new-sub-folder" link would give them the impression that those are different. Maybe this is a distinction that should not be made.
