What if we had a shop stand/attachment that could go into/onto walls?
So right now we have where we can place a shop stand on the ground. Though, sometimes you might need more space, or something to fit your shop aesthetics.
If you had items for sale on your shop walls, players could see it really well, and shop owners could sell more items.
The shop stand thing could be a tether that you place on a block, and then it acts like a shop stand, and it would hang from the wall on that block.
Maybe a small laser beam, metal rod, something like that.
