Hi Aternos 
Team!
I am here to ask you guys to add this great mod called TekTopia!
Here's the link: https://www.curseforge.com/minecraft/mc-mods/tektopia
TekTopia is a mod by Tango Tek. It's a fairly new mod that makes villagers smarter and you can create villages.
Hopefully you will be able to implement this mod for us to play with.
