All three of the panes within the Library Browse window are expanded by default. Once Library Browse search results are returned, you might want to collapse the Search pane so that you can see more results in the Results pane.
To collapse an expanded pane, click the Collapse button in the title bar or click the title bar itself. When the pane is collapsed, only its title bar is visible. In its title bar, the Expand button replaces the Collapse button.
To expand a collapsed pane, click the Expand button in its title bar or click the title bar itself. When the pane is expanded, the entire pane is visible. In its title bar, the Collapse button replaces the Expand button.
