The current system for ratings (1 * --> 5 *****) is visually limited. The stars are 'old school' in appearance and they are not represented dynamically. i.e. If I choose a rating, say "3", I only get the number 3...unless I put in a unit...however, the unit will only show as "3 *".
I wouldn't mind seeing an update to this function that better graphically represents a real rating score
