I never used P4, but I've used P5 and like it. I'd like Judy/etc. to be a little prettier (I don't use them), perhaps they should talk with Sixus1 about packaging Adam and Behemoth or putting them in the download section at CL. What would I like. Better tutorial books. I've bought some (and have the manual, of course). The Poser 5 Handbook is pretty shallow, now that I've gotten the hang of things. Better library control (I'd like to be able to re-arrange libaries the way I can move favorite places around on Internet Explorer. I use NN most of the time, but I hate their manage bookmarks compared to IEs). Better "cancel this" for when I have a file that's a mess that I don't discover, though cntrl alt delete works well. I'm assuming that by P6 I'll be up to buying a new motherboard that will run twice as fast as this one, which will speed things up. I'd like to be able to do multiple saves/undos without having to do it manually, but I'm learning. I'd like windows compliant context sensitive help and windows help file help rather than adobe postscript help. I hate pdf help files, I really do. I've got a 19" LCD monitor and lots of real estate, but they still stink, not to mention they don't have the active linking and searchability that is so much easier with windows helpfiles. I'm impressed at the way that P5 makes P5 aware models so much better, while letting P4 and PP still able to handle the models (you can tell I buy a lot of stuff from Sixus1.com where all the models are done that way these days). Given the price on Amazon.com, I can't complain much about the software.
