I think it would be helpful if you could do more editing of trades. Prices fluctuate all the time it would be nice if you could add items to a now "open" spot when you sell an item. Same with what you are accepting, keys metal etc, would be nice to also have a heading such as " buying keys at 2.66" . headings could be edited as prices fluctuate. This could be a donator only function. Good incentive to get free loaders to give back
