Thanks Morgan. I had seen this a while ago and forgotten that it existed. Please take a look at this new screen shot. I changed the favorites slider control to one which mimics the iTunes 4 ratings control, only this one is continuously variable. I needed the UI space to make room for the new control as requested in the above link.
Please make suggestions for improvements. Much of this code is shared between Goldfish and Marine Aquarium so you'll benefit from your suggestions twice!
