Indescribably useful, although I need to correct my earlier review for saying it "practically combined CUAShader with ColorScale," as to hunt for alternate shader options you'll still need CUAShader. Even so, the organization of what you can do to various pieces of a CUA is so helpful, in particular the individual render queue adjustments which isn't on anything else AFAIK.
Still very much a low-key game-changer for long-time VaM users.
