It would be nice to be able to use normal Granite / Andesite / Diorite in the Stonecutter to craft Polished Wall, just like with it is possible with Polished Stairs.
I quickly looked in the code to see if I can create a pull request for it, but I wasn't sure where it is creating the Stonecutter recipes for those blocks.

I added it manually to the final version to make crafting those easier for me, but would be nice to have it natively in.
