For years now, I hardly use conforming cloths in Poser anymore (just the occasional accessories, gloves, boots, underwear .. small things like these). Everything else, I let the Cloth Room do. I always thought the the Cloth Room gives a much more realistic look and feel of the cloths, even on stills. For my workflow, I do not have many things to wish for, right now, just to make it faster and get a bit better collision detection. A nice little ad-don would be, that you maybe can stop the simulation in between, do a little corrections/push/pull (maybe with the tools of the Morphing Tool palette) of the clothing piece and continue the sim. from this point on again.
