More building objects should be rotatable and should be able to be turned in all directions.
For example current items that can't be rotated at all:
Chests
Shelves
Forges
Anvils
Lacking Rotational Directions:
Sinks - North/South facing is same and looks wrong when facing north
Some of these might be difficult to implement or downright impossible but some are fully possible with some Pixel art work.
