Helpful features for regular viewers

I am a regular viewer of the NA/EU LCS, as well as the Challenger series, and I have encountered a bit of a first world problem; I cannot keep track of the games I have watched. Yeah... horrible, I know. Anyway, my point is that I am most likely not the only one to have this "problem", but it could be solved very easily if you could add a mark /sign /whatever that marks the game as "Viewed" next to the games the user ('cause you would have to be logged in, naturally) has watched.

This way, I could avoid watching 30 mins of a game between Curse and TeamSoloMid, just to realize that I've seen this setup before. And that pink-bush-ignoring by Dominate. And that Baron. And that teleport-engage by Dyrus.

Still, love the sport:P and the streams, and the page. Keep it up!
