I was thinking about a new feature that would dig through your entire transaction history for duels, bets, etc, and would be able to calculate your total winnings / losses for each subject.
If this script or whatever form it would be in included items from item duels, this would make a player's transaction history much easier to read and see how skilled a player is.
If the result showed who the person beat and for what item this would be quite valuable in choosing who to duel and what not.
