Need help with Supernatural Brows

Those Things

I just installed Supernatural Brows, and now I can't find the brows. All the shapes and materials are in my content library, but they aren't showing up in my smart content, and I cant find the brows themselves at all. I feel sure that I must be missing something. I've checked under hair, of course, but also accesories, props, materials, shapes, and everything else I could think of. So now, I'm asking here!

Those Things

Except, "anatomy>external" which I just checked, and there they are. Seems a strange place to put them. Shouldn't they be under hair? Ah well, at least I found them!
