vice, the KDE device manager pops up in the system tray area of the KDE kicker. Although it looks very much the same, the developers have introduced a huge number of changes to the device man- ager in Version 4.4. When you mouse over a disk or CD/​ DVD icon, the device manager displays an additional information bar showing you how many actions are predefined for the device (more details of this later on). Clicking the plug icon on the far right mounts the medium without performing any other actions (Figure 8). This two- click trick takes less than a second – a considerable time savings compared with giving a mount command at the console. Figure 4: The new widget dialog was born at the Google Summer of Code.
