I'm trying out KDE4's activities, but one of the problems I keep having is the Plasma Toolboxes' (cashew) menu loses "Configure Plasma" and "Zoom Out".

How do I get to "Configure Plasma" (i.e., Use a different activity on each desktop) when they are no longer on the Plasma Toolbox?

How do Activities and Virtual Desktops work together? Do you use one or the other? Or, can each Virtual Desktop have multiple Activities?
I'm having difficulties trying this because KDE4 seems to lose the "Configure Plasma" option :-(

Reference: KDE Plasma

OpenSUSE 11.2
Kdebase4 4.3.1-5.6.3

Thank you.
