Hear me out, I saw a similar comment, but I'm NOT asking for you to make the vanilla double slab block item available. I'm asking for a chisel variation of smooth stone that looks EXACTLY like how a double smooth stone slab block would look in the world.

Now this would do a few things.

1. EnderIO conduits would now be able to have a non-glitchy AND full block conduit facade for Stone Slabs.
2. Applied Entergistics would now have a cable facade that would work with stone slabs.
3. Open Modular turrets would now be able to camo the turret base as a stone slab.

And there is probably so much more compatibility this simple block variation would add. Building a base with stone slabs for the ceiling and floors have been a major pain when it comes to hiding cables, turrets, etc!

So I would highly recommend adding a stone variant that has the same texture as 2 stone slabs stacked on top of eachother.
