Block Shaper
Load a plain block and it offers every shape that material can take: slabs, stairs and more.
The shaper has no recipe list. You load a block and it offers whatever shapes that material supports.
Materials that shape
Rock, dirt, grass, regolith, ice, snow, crystal, Metal Hull, all three woods, all three plank colours, and Glass.
Slabs of the same material stack into one block, and stairs come straight or as corners and can be placed upside down.
