Makes the YouTube video player shrink into the bottom right corner while scrolling.
When scrolling down on a YouTube video, the player will minimize into the bottom right corner.
This means you can still watch the video while you're reading comments, etc.
This works with both the HTML5 and the Flash player.
I've disabled the ability to seek/skip through the video in the mini HTML5 version (it's actually hidden now) because YouTube's HTML5 player doesn't like the smaller dimensions of the player and the seek bar messes up.
