Touch momentum?

[SilverGreyStar]

This seems to be very much what I'm look for with an extremely easy-to-use interface (good work!), but what I'm missing is "touch momentum". Simply I want the user to spin the wheel by swiping across it quickly, and I don't want the user to be able to cheat by swiping it just a little bit to manage to stop the wheel at a beneficial choice for the user, so when the stopRotation event occurs I would like to be able to see how many times the wheel has rotated since the user stopped the swipe, and if it's above 5 (for example) I consider it as a valid spin.

I also suspect a "friction" property controlling how fast the wheel will slow down would be good to have.

Is this something you're willing to implement?
