Changing Grid Position
Moving a widget from one grid cell to another may simply be performed via mouse move. The precondition is, that selection by mouse is switched on for inside the container widget.
Selection by mouse will automatically be activated after:
Button 'grid' doesn't switch on the mouse selection. The mouse selection may be activated via menu 'Mouse ON'

When the menu shows 'Mouse OFF', the mouse selection is on and may be switsched off.

If a widget can't be moved by mouse, because it's hidden behind another one, it may be lifted to the top position by button 'lift'

And of course, when the detailed layout is switched on via menu 'Layout ON', the widget may be positioned via row and column
