Put parameter dial panel back into main Poser task a la P4/PPP so Windows' overhead doesn't need to get involved in basic (and time critical) intra-task communication. Remove CP for same reason. Update the Mac-to-Windows porting library to use current Windows APIs (that Win95 one MetaCreations and CL have used forever must be fully depreciated by now). Fix the various file handling bugs that screw up Windows - eg. closing folders opened to search for missing textures (the infamous "Folder Lock" problem). Keep track of virtual memory, and stop requesting it when you go beyond addressable space (2GB). IOH just make it a "well-behaved" Windows application. Sure I'd go for application speed up, new features (maybe), and a real UI, but all are quite pointless when the app is basically at war with the underlying OS! :-O
