Hello Aternos team ! 
Today, I would like to request the addition of a mod : Novablocks, for Minecraft 1.12.2
Novablocks is a relatively simple mod that adds cosmetics and new blocks shapes to your game experience.
For instance, it adds slabs, stairs, and even new shapes like slopes, half slopes, and some other narly features like a spacesuit, platefroms, some new fences...
It's really fun, and even handy to make any build tons of time better.
Here is the link to the mod : https://www.curseforge.com/minecraft/mc-mods/novablocks
Thanks in avance, have a nice day !
