There are some news concerning applets for the embedded Plasma I mentioned earlier. There are two new plasma applets in the playground (trunk/playground/base/plasma/applets/embedded-ivan/) - one that shows the title of the currently active window (needed since I intend to remove the decorations of main windows) and a simple task manager/application launcher which is on the left.
They are not fully operational yet, and have no documentation on how to set them up, so don’t even bother. I just wanted to say that they exist. :D
The task manager/application launcher contains a predefined set of icons. Each icon represents one task or application. And when you click it, application is started, or in case it is already running, it is brought to front. Some say that MacOS X has something similar, but I wouldn’t know, I haven’t tried it. (please skip comments about OSX… they might get deleted instantly).
