Great software, I'm using it more each day! Just downloaded the new version.
One feature that would be nice would be a control that allowed you to specify the number of rotations for a sprite/bone when animating, or at least specifying a rotation higher than 360 degrees or a negative rotation value. I find it tough to animate the rotations for the sprites/bones accurately. And I get weird results using the angle widget currently available, like the bones/sprites rotating in the opposite directions.
Another feature would being able to change the timeline to Frame/sec.
