Im not sure why people think the cloth room is so complicated, in my experience you rarely have to change any settings there. And if you do its very few of them. Otherwise its pretty much just to add the objects that you wish to collide with the cloth you have to add. Especially if the cloth is already made, then the vendor should have already set all the settings.

"But I do think that the cloth room, once the Poser team irons out a few more wrinkles and makes it more user friendly, and the hair room have the potential to be big marketing tools for Poser."

What they could do was to add predefine cloth settings, so you just selected the type of cloth you wanted in a list. But besides that i cant really see how they could make it a lot easier.

I do however wish they could improve the hair room, but then again these are really complicated in other apps as well and very hard to get good results with. Meaning the tools for working with dynamic hair are not easy to use to get something good out of. Also why you find very few tutorials on how to actually style hair for dynamic use, they are pretty much all just "then you can add hair or fur to this ball, just by doing this and that" but never how you create something that a human would wear, at least thats my impression :D
