The Meaning of Life, the Universe, and Everything.
Similar to different types of fences and doors, what if we could have different crafting tables and furnaces, based on the materials used to craft them?
For example, we could have an oak wood crafting table, a spruce wood crafting table, etc., or a cobblestone furnace, granite furnace, etc.
It would serve no purpose other than giving us a few more decorative blocks to build with. I think it would break up the monotony of having the same two textures everywhere, and it would make interior design more interesting.
I'm sure someone else has already thought of this. What do you guys think?
