What is the Zooming User Interface (ZUI)?
The Zooming User Interface, or ZUI, is another component of Plasma. It enables the user to group different groups of plasmoids together, and to quickly switch between one and another using a zoom-and-pan approach. Notice that at the time, although significant improvements have been made, this feature is still under heavy development and may be fully functional only with later KDE SC 4.x releases.
