When I rotate a subject, it'll be rotated in all of the frames (frame mode) and there isn't any shape control in timeline mode. Normally I have to make different layers for one subject and change its angles, that's very inconvenient.
This is something that can be easily accomplished in an actual video editing application like Premiere Pro/Elements or After Effects. You have easy options for keyframing rotation, scale, position etc. when creating an animation or video, not just position like in Photoshop.
