This version isn't really useful for any practical reason. It is for those who would like to see the new look of 3D Canvas. It's a more modern look, I think. I even made a new splash screen with functions along the lines of Office 2010. It was completely pointless, in practice, and my time could have been used better elsewhere, but it was something fun to do. Besides, doing it helped me to find a way to reduce the load time (by 5 seconds on my computer).
For this release, and hopefully this release only, you'll need to uninstall version 3D Canvas 8 before installing.
