idea - seller

exchange is nice. but when I wont build shop for best items, it must be so big. for buing 3 floors, is ok. but when I wont make seller too, it must be fol alls items (like 5 floors +3) .

It will be nice, if for seeling will be only one stack or npc or best will be just Chest.
for make it just like now, shift+click item in hand, write price/amout .
but will be great if admin can add more items to sell to one box. just svitch item in hand and click again to box.
when player wont sell somethings, then only take whot wont sale to hand, click, and write amounth.
