changing desktop themes in KDE4

I just updated to SUSE 11.3 and got the latest version of KDE 4.
I’m not thrilled with the default theme (the taskbar running applications are really fuzzy) and would like to install a new one, but there isn’t anyplace in the settings menu to change it. Did I miss something?
How do I change the theme?

System Settings > Appearance > Style > Workspace Tab
