Quote - Poser should have its own inside graphics editor  ...

Now THAT is easy to accomplish. Just like Poser doesn't have its own Python editor, why not put an option "Set graphics editor" in Preferences, and launch your graphics editor of choice from the Material room loaded with the texture you want to edit? Even realtime updating to the Poser preview window isn't that hard to do.
Cheap, easy, and flexible - you just use the graphics editor YOU like, not the (probably very simple) one that the Poser programmers can put in. You'll have all the abilities of Photoshop, PSP, Corel, whatever you want.

The same goes for modeler plugins. It's not that hard to launch an external modeler loaded with the 3D data that's currently within the Poser workroom. Admittedly more work and more complications than with a grapihcs editor or a text editor, but it can be done in reasonable time and for a reasonable price.

Most people forget that Poser already has sort of a way to support external renderers. Anyone ever used RIB export? (I didn't, but one of these days I'm going to try it out. Renderman compliant standalone renderers can be had by the dozen.)

There's only one 3D program being rewritten from the ground up AFAIK: Lightwave. And it has put back new features in Lightwave for a year or two, so now Lightwave users are complaining that their app isn't keeping pace with the others. While a full rewrite of Poser would be very good from a modern programming viewpoint (the codebase is some horrible 1990s spaghetti code, AFAIK), it would take several years to bring a rewritten Poser up to the functional level it has now.
See DAZ|Studio. Started several years ago, and still far less capable than Poser. Although the core is far more modern and far better programmed. In another 5 to 10 years, DAZ|Studio might catch up.

No, what I would like most in a next version of Poser is full Python support. wxPython accessible from PoserPython itself. Or even better, Poser accessible from an external Python environment.  And, of course, all of Poser's functionality exposed in a Python API.
Making the Poser SDK freely available to registered Poser users would alsi be an very clever move. There's a lot of talented programmers out there, let those make the plugins and extensions for Poser, they'll come up with functionality SmithMicro never thought of....

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
