AE has this weird behavior where it jumps or scrolls when i click to expand a set of properties (see image below). Every time it happens, I have to pause to get my bearings before continuing to work. Why would I want a set of controls to suddenly rearrange themselves whenever I click something? I don't need help scrolling... I have a little scroll wheel for that. I can't help think that violates some general UX design principle.
