Full Slabs
 
Vertical slabs and mixed slabs for modern Minecraft
Features
- Vertical slabs that just work — no new recipes or crafting steps.
- Mixed slabs: two different slabs in one block space, with per-half breaking (KleeSlabs-style).
- Single codebase for both loaders through Architectury.
- Additional compatibility added for Mo Glass and Blockus.
Note: Mo Glass slabs cannot be mixed.

How it plays
- Placement modes: cycle between three placement modes to control how halves place.
Bind in Controls → Key Binds → Full Slabs → Cycle Placement Mode.
- Overlay: a lightweight overlay shows which halves will be placed or broken.
Bind in Controls → Key Binds → Full Slabs → Toggle Overlay.
If you’ve used “vertical slab only” mods before, Full Slabs maintains that simplicity and adds mixing and interaction affordances on top, without recipe clutter.
