I have some.  A customizable button bar, similar to what is in most browsers, for example.  That would be a huge time saver not having to scroll through the menu bar constantly to get to common tasks.

Also, a better gismo for the direct manipulation tool.  Something with axis selection, like most modelling programs have.

And finally, better graphics performance, possibly even support for DX11 with the GPU offloading.  I have a fast, custom built and way overclocked system and can run the newest games with graphics cranked, not to mention no problems with other 3d applications, but doing something as simple as moving an arm in Poser gets jerky.
