KDE Plasma Netbook Shell first made an appearance with KDE SC 4.4. The second version is already on its way with KDE SC 4.5. KDE developer Marco Martin, gave a brief preview of what to expect from the KDE Plasma Netbook Shell 4.5.
Here it is:
The Shell has been receiving a lot attention to make it faster. The Shell, along with the Launch and Search activities, have undergone several optimizations. This should make the interface a lot faster and responsive.
All the Plasma scroll areas, uses brand new code to handle the touch and the flicking in a much better way. To improve both the looks and the usability of it, the widgets now appear perfectly aligned in a 2×2 grid, although you can still create a custom number of rows and columns. Interacting with widget will make it expand to take up to the whole screen height, so offering a “maximized” view of it.
Search and Launch
A different way to fetch the data used in the menus is being used to make it more accurate.
Drag and Drop
Drag and drop support has been added extensively to make the interface more intuitive and touch-screen friendly.
Marco also published a couple of videos showing some of the things mentioned above:
