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.
