There are few blocks which should get recipes in Stonecutter.
Some blocks from this mod already have Stonecutter recipes, but not all of them. Here is a list of those lacking blocks:

Sandy Bricks
Charred Bricks
Magma Bricks
Duskbound Block
Midori Blocks
Shingles (those blocks made of Terracotta)

I would greatly appreciate if you added those lacking recipes to the mod.
