Built in, dedicated Poser file editing system. Poser needs to start incorporating utilities that have traditionally only been available via 3rd parties. I think that the introduction of Dependant Parameters was a step in the right direction, although, considering how long ERC was being utilized by savy users digging around under the hood, I don't know what took them so long to introduce the feature. Poser requires too much hoop jumping and esoterica for the creation of content on a serious level... it's almost as if, because of an inherent reliance on outside content and the economic system derived from such, Poser is deliberately unwieldy for the "average" user in such matters.

What Poser does not need is to try and be Vue.

See, and I think this kind of thinking is just silly.  I keep coming back to Poser because it's good software to do what I need to do.

Why do you want to stare at the same screen, doing the same thing over and over again? 

Me, I'm happy to close Poser once in a while and open PFE, or PML, Morphing Clothes, Auto Group Editor, Silo, or ANYTHING BUT POSER.

Do you want them to replace Photoshop as well?  Texture painting inside Poser?  I think most folks will tell you that any program which tries to do it all, does a lot of nothing well.
