Unwatch

I would like to request an "Unwatch" feature. It would be one of the options when clicking on a video next to Play, Add to Queue, and Cancel. Why? I'm sure this has happened to more then one where there are times when you click on a video and it won't load for some unknown internet related reason. The problem being that even if it doesn't load Zinc considers it as "Watched".

So with this feature you can go back and click "Unwatch". This is useful for people like me that watch a lot of internet video and can't keep track of what videos didn't load =)
