Topic: Indicator for tradeslist when trading

First time poster, apologies if this was already brought up. With the many many versions of some cards and I don't memorize the card numbers, it would be nice to have an indicator of some sort to show what item is already on my tradeslist. Since I usually do trading opp first, I see they want a card I have, then I go to search it in a new trade and am like, crud, so many versions. Same goes for their side as well. Even if it's a little "!" in the corner denoting that it is part of their current tradeslist, so nothing crazy. Just anything to separate them.

Thanks!
