About

Auto Slabs

Automatically generate vertical slabs for every instance of SlabBlock. Supports Vanilla, as well as any mod that adds Slabs.

AutoSlabs Showcase

This mod also adds KleeSlabs functionality, so you can choose to break only half of a double slab block. Shift while breaking a double slab to break both parts of it at once.
