The "features under development" topic didn't specifically note this, so I figured I'd mention it... It'd be really nice if the item/currency trading was based on buy and sell orders rather than having to sell the entire stack of items to a single player. It would make buying things easier for newbies (since people tend to list items as large stacks rather than single items, making it harder to afford) and in general make trading go faster since you don't have to wait to find someone willing to buy the exact number of items you're selling.
