Well, I was going to make this one myself, but I don't have the time to do it, so I'd love to see someone else implement this idea! Basically, the idea is to restrict global shops to a single sign to stop cheapness (buying anywhere) but keep the usefulness of infinite stock. You place a sign with a special identifier to make it a sell or buy sign. It then changes into a list of item names. The sign gets another placed next to it that lists prices. Every time the sign is hit, the prices/item names scroll through the list. Right click to buy the item. The sign would hook into iConomy/SimpleShop to get currency and item prices. Does anyone want to do this?
