I apologize if this has already been suggested.

A useful feature to have would be the ability to see a list of your trade history with a specific user. Having a list of links to previous completed and cancelled trades between you and Trader_X would be great. Perhaps it could show up on the user's profile page as a simple list of links. Otherwise a dedicated page maybe that could be linked to in the side column (Email, New trade with Trader_X, View Trades, *Trade History*, etc...)

Also, a big thanks for all the work you've been doing.

Cheers

Good idea, the trade listing page could use some love.
