Thread rating different star colors
 

I would like to have different star colors on the thread rating depending on whether I rated the thread already or not (similar like NetFlix does it).

For exmaple, if the stars are yellow, it means I have not yet rated the thread. If the stars are red, I have alreadt voted the thread.

It happens very frequently to me that I try to rate a thread and get a message that I have already rated. Therefore it would be good to see if I rated already by the color of the stars.

I wold be happy to implement this myself, but will need some guidance.
