I whole heartedly appreciate KDE devs for thinking of and implementing the Similar to this feature for widgets.
My favorite distro now defaults to Icons Only Taskbar which I hate because it does not let me see which window is running which tab/directory etc. Now all I have to do is right click on the widget and select similar to this option. It automagically changes into the normal task manager.
Thank you so much for this.
Learned some really neat shortcuts fom the comments :)
