SDM UI Lib Mod simplifies the creation of custom user interfaces for other Minecraft mods. This is a library mod, which means it provides tools for other mods to use. It works as an alternative to FTB Library for SDM mods. By itself, the mod does not add any new content to your game. You only need to install it when another mod requires it.
