One of the recent interface tests I did was a trade offer submission.  Came across a mnemonic conundrum.  When posting offers to trade it may not be intuitive to use the two-column representation.  We’ve gotten very used to seeing price tags below an item to mean price that it’s worth / that you will exchange.  So I think I will make a 3 tabs or views of the trade offer panel: “WTB”, “WTS”, and “Trade”.  The trade interface will be more like what you see below.  The WTB and WTS will have a slot for a single item and then the offer price below.

Anyhow, this is my little drag-n-drop screenshot for the first test I did yesterday:
