Greetings to all.
I am new to Linux and my first approach is fair with Mageia 7.
I think there is a problem (bug) in the KDE Plasma directory that I am using.
When I told the main panel to hide automatically, I could not see it again, at all.
It should be understood that if the user wants the panel to hide automatically, this does not imply that he does not want to see it again.
I could not see or manage it again, so I had to recreate A NEW PANEL.
Now, as a result of the creation of the new panel, in the section on the addition of Graphic Elements, now the graphic elements panel has more than one installed, or in other cases up to three.
But I can't see the panels or the panel (if there is more of the new one that I had to recreate) that contains them (to the other graphic elements).
How to remove panels that are left over and that I can't see?
