Maybe it's because I've been a user of this code since it was RayDream, and it's what I learned 3D on (though I now do use C4D and Lightwave), but I find the different rooms easy to use.  Yeah, I can see how it's annoying to not have certain tools in the Spline modeler that exist in the Vertex modeler, but since I'm kinda wired for this workflow, it doesn't bother me.  I just know what I can do in one modeler versus another.

That said, there are a lot of things I'd love to have in C7.  One would be external geometry reference.  Similar to how AfterEffects works -- it doesn't store a complete version of every layer you have within the AE project, but rather references the external file.  That way, the AE projects don't get enormous.  The project I'm currently working on has some gargantuan Carrara files because Carrara has to copy the entire model into the .car file.  Alas, I doubt this will be implemented, though, because I'm sure it's a major rewrite of the code to make it happen.

Overall, I'm really happy with the additions to C6P.  It's a remarkable piece of software, particularly when you consider its price.
