Each Pane available in Ultra Recall serves a specific purpose.  By default, they are all visible and docked to the main Ultra Recall application.  Some of these Panes are Selection Panes; the others are Dependent Panes.

 

Which Info Items are selected in a Selection Pane determines what is displayed in all the Dependent Panes.  Only one Selection Pane can be active at one time; the active Selection Pane will have its selection visible.
