I think we should have a new button in the "Library" section. This button will delete ALL the stuff in the library that has a usage count of 0. Recently one of my Mineimator projects has been OVERLOADED with textures, and there's about 1000000 stuff in my Library that has a usage count of 0. Please, make a button so I can easily remove EVERY texture with a usage count of 0.
Please I'm begging you, add this.
