Shulker Utilities
Shulker utilities is a Vanilla+ mod, that adds and enhances the use of shulker boxes. They are already awesome, but can be just a bit more awesome ;)
At it's current stage it's a very simple mod, that currently only allows for assembly/disassembly of a shulker in-world.
It also adds a shulker box cactus, which voids any items hoppered into it! A vanilla+ trash can :D
