I ain't afraid of no ghost, er, Material Room; in fact, I quite enjoy using it to create complex material setups. But, OTOH, I shouldn't have to go into it every time I want to use a different material set that's already been created. Additionally, Poser can't accurately tell which figure is selected most of the time in the Material Room, which is yet another reason why also being able to apply materials from the Pose Room would be an improvement.
