One of my panels is missing—how do I get it back?

If it seems like one of your panels has disappeared, you have probably accidentally collapsed it or resized it. The Task Wizard, Chart, and Insight panel can be collapsed by clicking on the double arrow icon button in the upper right of the title bar for the field (shown in the screenshot below). Click on the double arrow button to re-open the panel. Additionally, all panels can be resized by dragging on their borders—you may have changed a panel size without realizing it. Drag on the missing panel’s edge to restore it to the size you want.
