As far as I know, PBooost is about the only utility out there that can do something similar. You can't nest the folders like you can in P5 and P6, but what it does is allow you to make little "mini" runtimes that can be swapped back and forth. Check in the marketplace (I think it's still available here) in Hogwarden's store. Other than that, I don't know of any other organization utilities for P4/Pro Pack. Kate
