As KDE 4.4 has hit the stable update repositories for Fedora a couple of days ago, I updated my parent’s computer. While doing that, I noticed that some options have been moved around, noticeably the ones concerning the Dashboard configuration.
Some months ago, I wrote a post about “Configure the KDE Dashboard to behave like in OSX“; the options to configure this have now been moved to System Settings > Desktop > Workspace. Simply select “Show an Independent Widget Set” in the drop-down box and you are done in KDE 4.4.
