Facebook Video-by-Feed

@Facebook with this added feature, people can continue doing what they love to do the most on facebook, scrolling - while watching that video they've started! What d'ya think?

Current problem: A user clicks play and either stays there until the video is over or scrolls down too much only to realise he can't easily go back up to pause it and just closes the tab to re-open facebook. Of my friends, a good 80% are found to do that.
