A simple maya feature that I know everyone wants.

I want to add a directory structure of some kind to the hypershade window. FLAT organization for shader balls is lame! i want to have a nice little folder named "RigShaders" that only utility shaders for my rig should live in. "CharacterMesh" shaders for things actually on a character, i mean, duh! fuck it's been 11 freakn years and it's still a flat organization without any chance for rearranging shit!
