I am animating in CS4 using the new motion editor. I noticed that Alpha can have eases like 'smooth point, corner point' etc. applied right to the property keyframes, whereas motion cannot. It just give me the 'roving' option. I've had to create a custom tween and apply it to the motion track. Problem is, if I shift the main animation around, I also have to go into the custom tween to match the moved keyframes. What's the deal with that?
