Hi again, just wanted to let you know I changed the way toggling the sidebar works like you mentioned and I'd appreciate any feedback you have time to give? http://toogl.es/#/view/oFR4L6GegXA is an example link.
Nice. It's far more noticeable now. Perhaps you can change the icon to a smaller one when the video is full screen, just to indicate to user he is going to make screen smaller after clicking it.
