Great idea, but very poorly executed. First of all it breaks all the theater mode layout addons, & you'd have to watch it on their site instead if you want twitch theater mode. Secondly, have any of the dev actually tried to enable "Auto hide header" on YT & see what happens? It hides the damn header & there's no way to show it back to adjust the settings... Also every time you fast forward the VOD, it stops working completely until you turn it off & on again.
