I think a lot of us have been amazed by Apple's lack of interest in porting some neat features of the 2 operating systems that System X is descended from. My big ones are the lack of the ability to minimize into a title bar (I know about WindowShade X, but what about native support?!) and the shelf from NeXTstep (I realize that 3rd party Drop Boxes do this, but I hear NeXT's shelf had a lot more subtle features to it). I never really used either OS for a long period of time (I only played with Classic in school and GNUstep on Linux) what are your favorite missing features? And do you think Apple is just trying to find some flashy eye candy effects for them?
