I would like to, at a glance, see if it is more worthwhile to sell my items to buy prices or sell prices.
Sometimes I bring a lot of items to market and I like to either sell to buy orders or put up sell order depending on the spread between the buy and sell price
Lets say that my total fees to set up a sell order are 7% and my sales tax to sell to a buy order is 2.5%. I may choose a minimum spread to sell straight to buy orders and the rest I can add to the sellers market.
for example I may decide that unless I can make a clear 10% at the current prices that I would rather just sell to the buy orders. All these options could be selectable through fields in the application.
