Drag and Drop - To rearrange the boxes, drag and drop by clicking on the title bar of the selected box and releasing when you see a gray dotted-line rectangle appear in the location you want to place the box.
Box Controls - Click the title bar of the box to expand or collapse it. Some boxes added by plugins may have configurable content, and will show a “Configure” link in the title bar if you hover over it.
