Sizes of the video player

Hi, Jeff. I was wondering to me how great and helpful would it be if i could press a button and the video player would go to half a screen, like on YouTube. it's great for a couple of reasons in my case. When i watch your videos here, i do it in split screen, half a screen with the editor, half a screen on laracasts. In this situation now, the video is not so great, and i cant work on the project itself if I'm in fullscreen. Hope you could add the option for "cinema mode" or whatever they call it on YouTube. Thanks.
