With Better Slabs you can make slabs out of nearly any block in Minecraft. Now you can make stairs or walls or simply floors out of anything to fit your aesthetic needs.
When holding your new slabs you can change the mode that the slab will be facing, whether that means placing diagonally, sloped or vertical! Just press f9 or f10 with the slab in hand to cycle the modes.
Diagonal functionality allows for some designs that were not achievable without this mod. Now you can construct walls in all different directions and axes.
There’s even a mode that will turn all current slabs back into full blocks in one click.
