Tell me why... WHY!? Why is there no freaking mod for Sideways slabs or Sideways stairs? Am I right, like when you're building something and you need that sideways stair or slab to make it look even better. I think a mod for this should be added to the server for creative. Like it's a serious matter, I was recently working on something, and to make it just a bit more perfect all I needed was a sideways slab or stair...but noo.. this isn't here T^T.
or just build around the fact that you dont have sideways slabs available? You dont need a solution for everything if you can have a solution yourself?
As stated previously, if this mod was implemented into Creative, it'd have to be installed by everyone and not everyone would download. Resulting in another decrease of players. Use trapdoors for the time being, until Minecraft actually release this.
They're going to be implemented officially by Mojang/Minecraft soon, after several updates. You can view their snapshot versions under the "versions" section of the Minecraft Launcher. This is because a vast demand of builders who needed it, had sent their requests to Mojang/Minecraft on Twitter directly.
Then it'd be compulsory for everyone who joins the server to have the mod installed on their game since a plugin doesn't exist which would act as a "mod" for the whole server. And this whole thing would just add up to be a waste of time for everyone. ~Wiz
