Issues
Window List
No open programs show on panel:
Add the Window List item to the panel. In my case, the icons were still there, they were just squashed to one side.
Zoom
On several occasions, I have accidentally zoomed the desktop using Super, Middle Mouse Button, Drag!!!
To restore the desktop to a non-zoomed state, try Super, and rolling the Mouse Wheel until the desktop is OK again.
Note: I am sure there is a better way to do this, but I haven’t found it yet!
