Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
On one of the portuguese fellowship boards, someone suggested about statistics of finished games per opponent.
Right now we can see similar numbers when we go to the FinishedGames page on our opponent's profile and choose the option "show games against me only". Or, when on a game, it shows the wins/losses/draws of the games of that type between the two of us, below the game board.
But what we're talking about here is the ability to see (maybe on our profile, under finished games?) an option to display the results of all our games but sorted by player. That way we could see who we play against the most; who beat the crap out of us; who is a good opponent to chalenge for revenge; etc, etc, etc.
