I'd be happy to have a two or three window view (top, front, one side). And I think this would be best as an option (Open View Windows, perhaps, where you could have as many minimizable views as you wanted open, along with the edit screen - each open view window would automatically update to reflect changes to the edit window - and the contents of any one view window and the edit window could be "swapped"). The "perpetual" four window view on the Rhino demo threw me off the two times I tried to use it...
