It would be a nice feature if you could rotate the pallets depending on the angles they were placed at, so the boards aren't always facing east/west. This would make it so that the three boards on the top could face north/south if you are facing the right direction when placing the pallet.

Okay, so I have attempted to make each individual layer of a palette rotatable. I have almost accomplished this, every layer works except for the first one. I'll revisit this at a later time, you are welcome to make any pull requests if you'd like.
