I think the Morph Brush is the single best thing they added to Poser in years, and that reminds me, haven't tried the fixed update yet!
DAZ are losing customers for not having one in DS, I know that for a fact.

I'm surprised you don't like the Firefly renderer though.  I wasn't too fond of it when it first arrived because the way the shadows worked really annoyed me for some reason, can't remember why now, but the stuff I've seen done with it as it's evolved, and what people have done with the material nodes, is something that impresses me over and over.  I think it's a superb renderer, and it would be the icing on the cake if they could make the current renderer make use of the GPU to speed it up, because that's my biggest issue with it, speed (or rather the lack of it).

But I agree 100% about the animation tools in Poser, they're nothing short of a prehistoric joke!
