One of the more unique features of Kubuntu is that it ships with a replacement for the standard KDE Control Center program, called systemsettings. Instead of using a tree in a sidebar on the left hand side of the window, systemsettings shows a large menu of grouped icons for the user to choose from. A lot of people like it (and some people don't), but pretty much everyone agrees that it can be improved even more.
For the coming Edgy Eft release, Ellen of OpenUsability.org fame has done a card sorting experiment with real users (not us geeks!) in order to find out how best to organise the settings modules in systemsettings.
In the last week I've taken Ellen's changes and implemented them.
