The table of content shows for the current project all opened data sources and other scene settings, sorted into foldable lists. The small black triangle in front of a list changes it fold state. The plus icon adds data to a list, the minus icon in front of a list entry removes it. Some entrys show blue circular arrows in front of them, by which the entry can be reloaded. Single entrys and whole lists can be activated or deactivated by clicking on the sun or cloud symbols. Entries with three dots "..." behind its name can be left-clicked, to open a dialog with additional settings. Use drag and drop to change the entry order, which defines the drawing order, entries higher up in the list are drawn on top of the entries below. Entries with a location can be right-clicked, to move the camera over this location.
