Auto-play next on videos

Verge,

Sometime relatively recently your video player started automatically playing the next video when the current video is finished, with no apparent way to turn it off. This is tremendously irritating, and frankly is driving me to seek most of your video content on Youtube. I can see how some people might want to just blow through a bunch of your video content without interacting with their computer, but not everybody. I'd like to keep watching videos here, as I understand it's better for you with advertisers. Please at least add an opt out somewhere I can use. Persistence between videos (set once for my account vs. once for every video I watch) would be awesome too.

Hugs and kisses,

Bagel
