This is an addon for Sable, a mod that adds physics to sections of blocks.
The core of this mod is to add physics when placing blocks. However, theres so much more!
There is a config for basically everything in the mod, including using slime to stick blocks together, making blocks fall when not supported, AND MORE!
I'd highly reccomend Configured for editing config in-game!
Theres a tag for things that stick blocks (otps:sticky)
Oh yea theres also paintings I guess
