Native ST-Map Support
After Effects needs native ST-Map support to handle a myriad of compositing functions, but I need it to handle the Distortion & Undistortion ST-Maps from 3D Tracking & match-moving software like PF Track. This is a standardized work flow in Nuke and is seriously lacking in AE. I know that there are 3rd party plug ins for this, but this is a compositing program and should be built in.

AE should treat channels as channels, like Nuke does. Its not just RGBA that we manipulate!
Those user friendly designs are often degrading for people that appreciate control and intelligent setup. One button 3d camera tracker is great for kids, ok - its great for small quick and dirty jobs too, but insult for any serious compositor.
