-The main window is called the Program window and contains the timeline as well as the entry point for all menu driven operations.
-It is often just called the \textit{timeline}.
-The timeline consists of a vertical stack of tracks with a horizontal representation of time.
-This defines the output of rendering operations and what is saved when you save files.
-To the left of the timeline is the patchbay which contains options affecting each track.
-The patchbay is described in detail in the Editing section (\ref{sec:patchbay}).
-
-The \textit{Window} pulldown on this main window contains options that affect the 4 main windows.
-Default positions repositions all the windows to a 4 screen editing configuration.
-On dual headed displays,
-the Default positions operation fills only one monitor with windows.
+The main window is called the \textit{Program} window and is often just referred to as the \textit{timeline}. Here is where you enter the main menu operations.
+This timeline consists of a vertical stack of tracks with time represented horizontally on the track.
+It is the output of the rendering operations and this is what is saved when you run the File pulldown, Save command.
+Immediately to the left of the timeline is the patchbay. The patchbay contains options that affect each track.
+These options are described in great detail in the Editing section (\ref{sec:patchbay}).
+
+The \textit{Window} pulldown on the main window contains options that affect the 4 main windows. The first 3 options are used to display each of the windows in case one is accidentally closed. You can
+move or resize the windows as needed, save that particular layout, and revert to the default positions
+to reposition all 4 windows to the original screen configuration.
+On dual headed displays, the \textit{Default positions} operation only uses the one monitor to display the windows, but as you
+can see in the \textit{Window} pulldown you have more options to change that. Usage with dual monitors is
+explained in \ref{sec:multiscreen_playback_configuration}.
