US Patent 11803292 User interface component and region layout control

An embodiment facilitates user control of user interface layouts. A layout diagram visually and diagrammatically represents a current layout. The layout diagram includes layout diagram regions which correspond to user interface component regions in the current layout; the user interface component regions have user interface components as occupants. The embodiment gets a choice identifying a traveler component and a destination region, with the traveler component being an occupant of a source region. The embodiment modifies the current layout of the user interface to produce a modified layout in response to the choice, and updates the layout diagram to match the modified layout. Interaction is improved by diagrammatically showing the user the results of possible layout changes before performing any of them.
