Then you can use the favorites folders to organize your content even further.  The purpose of this feature is to localize content icons from several runtimes into one specific common folder.  For example, you use M4/V4 quite a bit but they reside in separarte runtimes.  Major headache opening one then the other.  Under favorites, create a folder entitled models (or whatever you wish) and save the icons there.  Both in one place, eliminates searching.
