The "Vanity Folder" thing is a tricky one. On one hand it's much easier to credit a merchant/freestuff provider if you know you picked the prop (or whatever) in the TrekkieGrrrl folder. On the other hand, that folder may be enourmous and there IS a good deal of sense in dividing stuff after what it is rather who made it.

Personally, I do both. My PBooost has divided my Runtime in folders according to content (V3 clothes, David Clothes, Scenery stuff and so on) and in THOSE runtimes/folders thigs are sorted like the original zips were doing it. So ion some folders there ARE a lot of ! and !!!! stuff. And yes, it's a PITA. But I've used the space thing myself, not on folder level but inside the folders, to keep things together. For instance the major texture for a character should come before eye colours or nailpolish, at least in my opinion, so that would typically be prefaced with a space.
