I just discovered tiled window managers like dwm. But they don't implement advanced capabilities I am used from kde. But then I had an idea:

There is this composite feature: You can see a little live window at the right border even if the real window is not active and behind your actual work. So I like to see some TV News but also working on eMails at the same time. As I do mostly hear the news it is alrigth for me to have this little live window at the right border - and I can see the live video stream.

But I can not click this picture for activating the kaffeine main window. Is there a plasma widget already available that acts like a window tasklist on the panel but can present a live miniature picture of that thread?

So you can have a wide panel at the right containing the window tasklist having live miniature pictures?

So, if I understand you correctly, you are asking for a task manager that show previews of the window instead of icons?

Yes,
that would introduce the feature of tiled-window-managers to see some more windows uncluttered. But your work would be as ever in a not mini window.

And additionally I would like that the order these mini windows are displayed reflect the task switch order.

In this way you have some functionalities of
- task-list
- task-switcher
- tiled window manager

I would like to give a third of my ultra-wide screen for this.

Probably won't fully satisfy your needs but have you seen the "Thumbnail Aside" desktop effect?

Thumbnail Aside desktop effect did bring me the idea of this feature request.
