myEDITED: How Do I Edit Or Resize A Dashboard Widget?

Click the three-dot menu in the top right of the widget. 

From here, select Edit widget.  For configurable widgets, you can adjust metrics, sorting order etc, but module-specific widgets are not customisable so you will just be taken back to the preview page.

You can also Remove the widget if it is no longer needed. 

Use the 8-dot icon to drag and move the widget anywhere on your dashboard.

You can also expand or reduce the widget size using the highlighted icon in the image below.
