Why is it not possible to separate the dimensions of the top position in a rectangle?

Just to add to the votes, I NEED to be able to separate X and Y in ALL of the position properties, not just in the "Transform" sub-menu.

I'm trying to get realistic character animation, Pixar style, as per my training through Animation Mentor and experience beyond.

But I can't do exactly what I need with, for instance, the Puppet Pin Tool because I can't separate X and Y.

Even something simple like the bouncy ball - as per this video - http://tv.adobe.com/watch/learn-after-effects-cs4/animating-precisely-with-separate-dimensions/

If I make my ball connected to a Puppet Pin, I can't properly animate a bouncy ball. Imagine that difficulty multiplied as I apply the same problem to a full character rig with arms and legs. It seems pointless having the Pin tool at all if I can't properly control it.

This is a big problem, as I've been using Adobe steadily for six years since CS3, and I've just discovered the graph editor has been removed from Flash, per CC. Where else can I go if not at least to AE?

If I can't get these controls over my animation, I'd have to either animate frame-by-frame, or move over to another product, which would be a shame because I love Adobe and I know it's possible.

I know I'm in a minority, but PLEASE consider adding the "Separate Dimensions" functionality to ALL aspects (I'd even wish for it on rotation, scale, etc.) I would find this not only extremely useful but actually necessary to do what I am trying to do.

Thanks,
