I have marked my favorites by adding a number to the name. Say I want the rig EVH2 as one of my favs and assign the midi number 012 to it...then I change the rigs name to 012 EVH2 too. That way I find all my midiassigned rigs as a sequence sorted by name. When I like a rig but haven't finally tweaked it yet, I put the number 200 before it's name. That way I can easily find these rigs sorted by name. Think about it. It works well for me.
