I don't mind a limit on the number displayed. Maybe options to set limits at different numbers? Like display 4, 8, 12, 18, etc.? And by random do you mean their display order is randomized? So if 4 are displayed and a user has 10 total it will randomly show any of the 10 at any moment in time in the spot? If so I think an option of randomization or a set order users chose would be a nice idea. I know some of my users would like it being randomized but I know others would like to display the items in a specific order. That's one of the minor issues we have with user Trophies&Medals as the custom items on our site. Users can't just arrange them to their liking.
