It would be nice to copy/paste keyframe placement between tracks. In this case, I changed the levels in certain areas of a music track that wasn't finished. Instead of going back and reinserting said keyframes at the same values in the finished file, it would be nice to select all keyframes in the unfinished file and paste them in the new file. I've tried doing this and all it does is copy/paste the actual file instead of its keyframes.
