I've got a few applications pinned in my Kubuntu installation:
When I open one of them, the pinned icon goes away and is replaced by the running application further right:
This makes it a little tedious when I want to open more instances. Although I can click the mouse wheel on the running instance as a workaround, I'd like something like the old Windows quick launch where the icons remain there and you know exactly where to click to run a given application.
I've seen this answer which seems to address the same problem. However, I don't see any "Add to Panel (Widget)" and I have no idea how to add the mentioned "Quick Launch" Plasma widget. I would appreciate some more detailed guidance on how to get this working. Thanks in advance.
If you have Kubuntu 20.04 i took two pictures for your problem.
