KDE3.5: window list with multiple desktop structure

Note how next to the pager in the KPanel there is an arrow one can click to bring up the entire list of all open windows, structured by desktop; that is what I miss most (or have not yet found) in Mac OS X Leopard. It is so much easier than first pressing F8 to go to the Spaces view, then trying to locate the desired (now smaller) desired target window amongst all others. It's even worse on Mac if the target window is not on top of its space, in that case one has to also use the Expose F9 to reduce the Window view even further and hunt amongst tiny little windows (admittedly with a title on hover).
