I'm running Ubuntu Studio 21.10, KDE/Plasma version 5.22.5, and for some reason the default alignment of the default widgets, "system tray" and "digital clock", on the upper panel, lose their right side of the panel alignment, on a reboot, and move over to the left side against the pager widget. I move the systray and clock back to the right and they stay there till I reboot, then its back to the left. Is there something I'm missing to LOCK these widgets in the desired locations? Also, can the default panel be moved to the bottom of the screen? Been using earlier plasma versions which default to the panel being on the bottom of the screen..

Thanks Dave

There has to be something between your pager and systray. For example, taskmanager, a flexible space. Everything is done by right click panel>edit panel. So is screen edge. Right click panel>edit panel>screen edge.Simply drag it to the bottom. You can set the height if you wish.
