Beautiful! I love the collapse/expand feature too.
One problem I have with the UI is that I feel the left/right arrows should ONLY be for going to different horizontal locations on the timeline, but they scroll through vertical locations as well if they are all at the same time. This was unexpected. Perhaps up/down arrows for the vertical navigation?
