PBoost is a program that sort of adds another layer of file management to Poser. For instance, I have all of my Vicky 3 related MAT files in one "bank", and all of my, say, Mike 2 MATs in another. If I'm working on a scene with Vicky 3, I load up her bank, and I don't have to sort through any Mike 2 stuff I'm not using. On the other hand, if I'm doing a scene with both, I can just switch between banks as I need them. It's in the marketplace here if you want to take a look.
