Would you ever consider adding a sound for when you mark an image with a color? In our office, we sift through thousands of images together quickly (thanks to photomechanic). One thing tends to get in the way of the flow though. If one of us is controlling the keyboard and making the selections, the other viewer can only tell if an image has been selected by watching the color in the corner change, rather than watching the images themselves and hear an audible sound. A small ding would really help and probably speed us up even more. Waaaaaayyyyyy back in 2009 I could swear there was a sound but I haven't heard one since.
