BlockUI Mod is a technical mod created to simplify the creation of various interfaces within the game. It can be used by mod authors to make the process of designing interfaces for different blocks or tools easier and faster. For regular players, this mod does not offer any practical benefits and should only be installed alongside another mod that requires it.
