All widgets are configured using a configuration overlay, which is displayed:
•On electing to build your own widget. The new widget is added to the bottom of all existing widgets with the configuration overlay visible.
•On clicking Configure at an existing widget displayed within a dashboard. The configuration overlay is displayed over the widget at its original position
The widget configuration overlay consists of a header, left-hand properties toolbox and right-hand preview panel.
A button facilitates the hiding and showing of the properties toolbox at some widgets:

The header is shared by all widget configuration overlays; properties and preview panels are unique to each widget type, and are described on a widget-by-widget basis.
Having added a new widget, or having made changes to its configuration, you can click the Done button to the top right to save your changes and show the widget in display mode.
