Hey ! I'm sure a ton of avid traders are out there that have multiple trades up sometimes need to cancel them, however in order to do that you need to click the trade link then click cancel this trade, then click that you are sure, then go back to the trade center, and finally go back to trade management to restart the cycle. This gets really tiring if you're cancelling 2+ trades. So! I'm suggesting a feature in which puts a check box next to all of your active trades in trade management, as well as two boxes at the bottom of your management tab that say "Cancel all checked trades," and "Cancel all trades." (Similar to the two buttons at the bottom of the inbox!) Upon clicking a few trades and clicking cancel checked or clicking cancel all trades, an "are you sure" tab will come up explaining that you will need to relist your trades if you cancel them all/the checked trades. This makes it easier for those that trade actively in the trading center when you change your mind or set up a bulk deal.
