This is more of just a fluff thing, and definitely not needed. However, it would still be kinda cool to have around. My idea here being, that you can go on your friend's list, and see that a friend is spectating a game. Now, if you don't wanna go searching for this game, or don't have the person he's watching friend's listed, it would be cool to be able to use your friend to spectate the same game that he/she is. Being able to right-click on their summoner name on your list, and hit the spectate game button, and watch the same game. Again, it's more of a fluff thing, and not really needed, but it would still be a rather nifty thing to implement.
