UPDATE: There are reports of YouTube UI experiments breaking this extension. I can't do much about this for now as i am not in the experiment and can't subscribe to it, sorry. --- Makes YouTube theater mode fullscreen, using the entire height of the browser viewport for the video player. Works for regular videos and for livestreams. - Page is scrolled to hide the YouTube header - Chat is also resized to occupy the entire height - Doesn't change the page when theater mode is disabled And that's it. A simple improvement to you viewing experience.
