A bouncing notification icon

I keep my dock on auto hide, and it would be great to have the option to have the app icon bounce once or twice when the Dock Badge label is updated. Sometimes my sound is off (for Campfire), and a single or double bounce would be an awesome way to get my attention when the status has changed. Obviously many people might find this annoying, so the user should be able to turn it on or off.

Absolutely love the product. Keep up the good work!
