No Double Slabs (NDS)
by k.eri
No Double Slabs lets a player stack one slab on top of another slab of the same kind, once the mod is enabled.
What it does
Normally a slab can only be placed on the top of a block, not on another slab. With this mod turned on, placing a slab on top of another slab of the same type is allowed, so the two halves form a full block. The author built it mainly to make spawn-proofing farms simpler to construct.
Key features
Stacking slabs
Once enabled, a slab can be placed on top of another slab, completing a full block in the same space.
Spawn-proofing farms
Slab stacking makes it simpler to build the flat, closed surfaces that spawn-proofing farms need.
Single toggle
The behavior is switched on or off by one setting, so the mod changes only that placement rule.

What the author says
The mod itself is pretty self explanatory. Once enabled, it no longer allows you to place slabs on top of another slab. The goal of this mod is to make spawn proofing for farms extremely easy. Great QOL Mod.
