Stone Walls!

We have Stone Stairs, Stone Slabs, but no Stone Walls like every other stone existing in Minecraft! It would be very nice to complete the set and be able to build with Stone Walls instead of always substituting with Andesite or something of the like. Thank you!

Side note: It would also be nice if there were a set dedicated to Endstone too, since we don't even have anything like that (The closest we have is Endstone Brick Stairs/Slabs/Walls, but those don't mix well with Endstone itself!) in the game either! Just a thought :D
