Ever overestimated how many full shingle blocks you need compared to slabs and stairs?

Or need a certain kind of block but the trader only gives you the others?

Or do you just wanna store shingles more efficiently (as long as you don´t plan on crafting roofing blocks)?

Now you can convert slabs, stairs, and blocks into each other without any loss.

Works with fire and blue, as well as red and brown shingle blocks.

Note: if you play with primitive survival, you first need to convert your "Better Stairs" into normal ones.
