Hello,
I wanted to suggest if possible to make, like there was in retail, the possibility to make "bulk sales" when you set up a sales shop. Basically, it was a little box you ticked in the window of "the setting for sale", that would make it only possible to buy everything that was presented in the shop. It was usefull when you wanted to make a sale discount for exemple to sell a full armor set (instead of only pieces by pieces ) or for another exemple say, 10 million Ancient Adena all at once (instead of painstinkingly have your shop all the time it takes to sell them one by one). Such feature was created at the time to boost exchanges and economy in game, so players could make discounts at selling or buying sets or quantities of a certain item.
Now I realise this is not a very important matter, and was only suggesting if it happenned to be something pretty easy to set up as it might boost some exchanges of items, and help the economy of the server. If it happens to be a pain in the ass to implement, dont bother at the moment :p
