2.5 User Preferences

I ran the pre-alpha version of Blender 2.5, as of September 15, 2009. You see the startup screen first, then I switch to the User Preferences window. After that, I hover over each menu item long enough for the tooltip to display. If there is a menu choice, I click to display all the choices. Remember, this is pre-alpha software. No guarantees that each and every feature will make it into the final 2.5 release, but this should give you an idea about what the developers goals are. I apologize if you're not a speed reader. You might want to pause the video often, read the tooltips you're interested in, and continue.
