We must exchange items with many bank checks when trading in these days. It is very troublesome to have to count many bank checks and to examnine them one by one. There are also some bad players who schemes frauds while trading. So I'd like to offer a few plans to improve these circumstances. (1) The idealest plan: to display the total amount value of bank checks in containers on a trade window or on a specific window for it. (2) A compromised plan: to introduce a bank bag. You can see the total amount value of all the bank cheks in it, with your mouse on it. A bank bag is necessary for players to trade items with bank checks smoothly each other. This bag would save such troubles as we must count too many bank checks examining one by one, and would prevent bad players from scheming a fraud with bank checks in trade. This bag can contain only bank checks in it. Bankers sell bank bags. New arts are not necessary, as the art of ordinary bags will do it. It would be much better for distinction, if the bank bag is dyed with a bright color like a salvage bag. (3) A safe plan: to introduce an identifying wand that can identify the total amount value of bank checks in a container. (*) I know that items in containers can be displayed in a listed view or in an inventory view on KR. But I'd like to offer these plans for players who play only with 2D client.
