sounds cool. assuming that LED patterns are easy to fire, ill try to do it soon-ish.

initial proposal for next release is to add the following options:
1) quickSnapShutterSound {default is none}
2) quickSnapSaveSound {default is snd_camera_shutter.wav}
3) quickSnapShutterLEDPattern {default is blink}
4) quickSnapSaveLEDPattern {default is blink twice}
5) quickSnapShutterCmd {default is none}
6) quickSnapSaveCmd {default is none}

what you can do, temporarily, is bind another action to the same sequence, to run a command that performs the led notify. it will fire roughly 3s before the picture is snapped.
