I like IK to quickly get things "into the ballpark." However, once they're there I turn it off and finess things using the dials. What I'd love to see for animation purposes is something that would allow me to only display the attributes I choose on the timeline. Once I've got a head or foot scaled, or face shaped (for example) I rarely animate that attribute. Once I conform clothing to a figure I rarely animate it seperately. However, on the timeline I have to scroll way up and down, bypassing all sorts of attributes that I'm not going to change, to get to the things I'm animating. That's a pain in the backside. It sound's like something like this product - where you display just what you want to work with - would be awesome for animators if it could be applied to the timeline.

Before they made me they broke the mold!
