Very nice! A minor niggle: the map in the sidebar doesn't react when the window is being resized.
Edit: also, the map seems to get stuck: http://i.imgur.com/YOVzJwz.jpg

What did you to do get that map stuck in your screenshot? Never seen that before.
At one point, it switched from "world view" to "US continental view" to show a hyperlapse from Miami, and then got stuck there in perpetuity.
Edit — or maybe I had a blackout and this is resize-related as well. It would make sense if I shrank the window, so half of the map got stuck outside the window. Never mind then :)
