	<title>Graphical User Interface</title>
	<para>This section introduces the Graphical User Interface (GUI). </para>
	<para>The GUI of RCE is composed of different views and editors (besides standard GUI elements such
		as the menu bar, status bar, etc.). Views can be (re-)arranged by the user. They can even be
		closed and opened again. Some views are closed by default, but can be opened as desired. To
		open a view go to: Window → Show view. </para>
