Agreed about tabs and split windows. I think they take over the window manager's job, and do it poorly. About the menu, it is nice, but not unique. Windows' Explorer, for example, shows it when dragging with the right mouse button. Options include copying, moving, zipping and actions from any registered shell handlers. That said, I think KDE is still the best desktop environment across all the operating systems I've tried.
