@Basic: Thanks for that little history lesson. I guess I got "untrained" by leaving poser for about 3 or 4 years between P7 and PP2012. Turns out the one character set I sold here for M3, around 2005ish, was also set up with mat poses. But that's because I didn't know what I was doing back then. 

I just don't like having a million folders to have to scroll through in one category. The one thing that makes the library categories important is that you can't save from within Poser to just any category, it has to be moved manually. Otherwise, if you want to save a pose then you have to have the Pose library open. Same with all the others.

I have two character/texture sets for Dawn over at Hivewire and I went with Material Shaders only for them and stated it up front. Got to train the average user to stop using them.

Yes, and that's all it should take. Just state that they are in the Material library on the product description, and in the readme. For the handful of people that actually read product descriptions or readme's. lol.
