I was looking recently for a widget that could display rating results, say as stars. I don't need any voting/rating functionality - just a widget to display number stars, based on what editor has put for a given content. The rating could be stored as simple integer field, which has lead me to an idea of creating new display widget for integer field. You could configure what kind of image (or any other custom HTML) should be repeatably displayed instead of the integer number, you could also set up another image to be displayed for another (maximum value - current value) number of stars - to possibly get an effect of bright N stars and then "switched off" M stars next to them.
I'm not sure if the idea is worth development, any thoughts?
