There should be a tick that says, "Have stairs and slabs." if you click on it it tells you what to name them. (It's like how armor works. it makes 4 items from 1 element, so this could be +2 elements from 1 element. (stairs and slabs.) There should also be an element where it's just a slab for blocks like gold, dirt (Don't ask.), bedrock, etc. (Same with stairs too.) Plus I'm ready for 2.x.x!
