KDE3.5: easy to move a window from one desktop to another using top-left corner window menu

Uses the context menu for the top-left corner of a Window, and shows named desktops clearly, and what is on them already. It's much faster than dragging with the Mac OS X Spaces (after pressing F8 and making all windows smaller, without even a nice text listing or named Spaces), which drives me craz(ier), because one has to remember what each Space is or was for.
