Are you using external runtimes?  If so, you need to add them to the P7 library.  When you click on the triangle that's to add a new collection category.  I'm using that right now to build collections of the characters, hair, props and lights I use most often so that I can access them quickly.  They don't have to be in the same runtime which is a great feature since my external runtimes are broken up by a lot of different things.
