Hello!
I think that would be good to add filter in trade tab. For example if I want to buy "Bronze swords" I would like to see only that in list. Maybe some button which opening window with checklist for offer and for cost items. Then it will be possible to do above written and also it will be possible to see all trades like this: "Bronze swords" for "Coins".
Hope you will add it and reward me with 10 pumpkins for idea
