I've been fiddling around with SMH for awhile now and it's a pretty awesome tool, and the most recent patch that adds multiple timelines for things like facial animation etc. is an incredible leap forward, but there are still some much-needed features that I feel would bring this tool a lot closer to a real professional animation program.

-The ability to copy/paste multiple frames at once. Right now we can only copy/paste individual frames one at a time. This makes animating something with repeating motions, like a walk cycle, really difficult. If we could select multiple frames to copy, it would help out a lot.

-The ability to import sound files so we can properly lip sync. Right now the technique used for animating spoken dialogue is the opposite of the way things are normally done in professional animation programs, where we animate first and then mess with the frames to sync the motion with the words. Being able to import a sound file so we can animate around it would make things so much easier to work with.
