Setting up 3 new VMs for my laptop. Most is going well. The only problem I haven't been able to solve is when trying to add workspaces to the panel in Plasma. Although I was able to do that in the testing version, I haven't discovered any way to do that here, and make them stay.
The panel needs to be edited before anything can be added, and I figured out that part. Then widgets can be added. But it must be kept open for editing or the workspaces disappear. Edit again, and they reappear. Stop editing, or select the "lock widgets" option, and they disappear again.
