A few idea's!
removing water from the options for liquid falling on the head in favor of maybe a jet of water being sprayed in the models face?
Adding in the ability to activate the redeems on both point redeems and bits.
Ability to add custom animations, not just items. And if you add this, maybe add in the ability to choose 'presets', and the presets just being the animations you have created, so that way you could say have a redeem for 1 throw and a different redeem to throw 10 items or 1000 items.
If any of this is already possible, please tell me where the info on how is located.
