Can SNAP! sync animations?

Just downloaded the SNAP! trial and it doesn't appear I can sync animations or do any kind of annotations. What if my course doesn't have audio? I should be able to sync my animations. Also I'm surprised I'm not able to add and sync simple annotations like arrows, checkmarks, rectangles to highlight things, etc. Seems like a pretty big oversight here. Am I missing something or is SNAP! in fact void of these functions?
