Description of problem: kde3 users got used to get desktop window list by pressing the middle mouse button against desktop. kde4.1 doesn't allow it by default, but not even with manual configuration. Version-Release number of selected component (if applicable): kdebase-workspace-4.1.0-3.fc9.x86_64 How reproducible: always. Additional info: installed from f9 updates-testing.
This feature is simply not present in Plasma, upstream KDE developers would surely love to hear at bugs.kde.org :)
