The standard setting in the Detekt viewer shows a large primary window (image below: mobile mapping data) with a secondary window (image below: map) on top of it and a side panel on the right. Both windows and the side panel can be arranged with a variety of options to suit the users' displaying needs.
Windowed view overlays the secondary container on the primary container. The secondary container can then be resized in the bottom right corner.
In the windowed view, the secondary container's position can be changed using the drag button.
The secondary window can be hidden completely. To show it again, click the button again in the center top of the primary container or select "Show Secondary Window" in the settings panel.
The side panel width can be adjusted using the horizontal slider, a click on the arrow button while hovering over it hides the side panel completely.
