channeLimiter runs in a non-modal window so it stays open while you work, allowing you to check the results of your limits in action as you adjust them. For full interactivity, hit the play button on your frame slider while you work.
Features:
Limit an item's movement within a Min/Max range
Limit channels to a constant value
Animate the enforcing of the applied Min/Max limits over time
