One of the best things about Poser 4 is it gave you the option of using it with the Poser 2 GUI if you wanted...

Poser 2 had the last reasonable interface for Poser but I do enjoy the new features such as shaders and morph brush and morph putty in Poser 7 as well as the Face Room when used with the Poser 5, G2 and Apollo figures. The multiple view ports that came in with PoserProPack  can also be usefull though usually I just switch cameras with the hot keys in a single preview pane.

I think a lot of people would like a hack to replace the Poser 5-7 interface but most don't know that Poser 2 had a perfectly good interface design that would work just great extended to the features and tools of the later versions if that was possible. Sometimes I use the Loader.py by ockham as a substitute for the libraries but I sure wish the other interface ellements could be controled with a retro interface.

There was a single-tabbed-palette UI.py I used for a while with Poser 5 but I don't think it runs with Poser 7. A simple python based UI for Poser 7 that controlled the posing like the William_the_Bloody's Pose Magic and Universal Morph Magnets and used sliders for trans/rot and scale etc. would sure be cool... I just would not want to give up channel nesting for the morphs.
