Hi aternos! Good day!
Can you please add "Side Slabs"?
Link: https://www.curseforge.com/minecraft/mc-mods/side-slabs
Description: Is very simple.
This mod adds vertical slabs from all types of blocks in the game, one for each type of vanilla slab. They work the same way as normal slabs, and form double slabs when placed together on the same block. Except they're vertical instead of horizontal.
Thanks!
