If you’re on current stable version, The move is not available, That’ll return with future update…
Although the remove applet option is moved from hovering over applet icon (In edit mode) to right click on applet icon (while in edit mode)
If you’re only right clicking on icon while on desktop - It’ll only give you configuration options and such depending on what applet you’re interacting with.
I see this a better change as hovering made the remove option go nuts for multi-panel setup…
But yea the change should’ve been more obvious that the remove option is in secondary right click menu inside of edit mode.
We discussed it here too - Was rearrange applet icons in panel removed in Plasma 6.5.6?
hope it helps
