Didn't see it in the other list, but Library Manager is very good (planning to upgrade at some point).  My other "most used" is EZ Skin, Morphing Clothes (seperate utility)   ...actually, that's about it.  I like Advanced Figure Manager, but it started causing a lot of error messages in P9, so I removed it from the auto-start.  (I miss the remove all morphs command, not sure how to do that otherwise?)
