I may just be missing where this is, as I'm new to this site. But to go along with an updated trade list / wishlist interaction could you implement something similar this (or tell me where it is if it is already there):
When you search for a card it currently shows 7 users who have the card in their tradelist. It would be nice to be able to expand that to show more than 7 per page. As well, it would be nice to be able to show the $$ value of what they have in their tradelist as well as the $$ value of what you have in your own tradelist instead of having to click on each user, and their feedback / number of trades. This is already shown when you click on the user, but it's kinda tedious to check through 20 people and see that what you have for trade is not what they are looking for. As well, it would be nice to be able to sort this expanded list by $$ for both you have and they have, and feedback.
