Supplementaries is a Forge mod, updated with the latest versions of Minecraft. It adds many animated and functional decorations, as well as useful and creative redstone blocks that fit well within normal vanilla Minecraft.
I've looked into it, and making a Fabric port would require to basically remake the whole mod so I'll only try doing it once I'm finish adding block to the forge version since I prefer adding new stuff that learning a new api. Please stop asking to port to older versions. Maintaining this one already takes up a lot of time and I'm not interested in supporting older, obsolete versions. Plus, even if I could port to 1.12, I still wouldn't do it since one more mod for 1.12 would mean one less reason to switch to 1.16, and I definitely would want the community to start moving away from that three year-old version, just like how that happened with 1.7.10.
