NURBS! And a feature found in Rhino, when you click in the top left of the viewport it maximaizes it. Double clicking it again will put you back to 4 view mode.. And you can resize the individual viewports and create new ones for custom views. I know many will (strongly) disagree with this suggestion.. Move away from the candy KPT interface.. I know it's beautiful and really cool looking, but it subtracts form functionality for being so candy..Make it more like a standard interface, so you can have more tools at your fingertips, without so much clicking to get there. I know some hate it, but Rhino's interface is the perfect 3D workspace. Once you get used to it, it's much faster and productive.. And it applies to other major packages as well..Just my opinions...
