+Project Outline View
+====================
+
+The Project Outline View is available as the second tab on the right hand side of the main window marked "Outline".
+The Outline View provides an overview of the novel structure, displaying a tree hierarchy of the elements of the novel, that is, the level 1 to 4 headings.
+
+Various meta data and information extracted from tags can be displayed in columns in the Outline View.
+To turn on or off specific columns, right click the header and select the columns you want to show.
+The order of the columns can be rearranged by dragging them to a different position.

+.. note::
+   The "Title" columns cannot be disabled or moved.

+The Outline View itself can be regenerated by pressing :kbd:`F10`.
+You can also enable automatic updating in the :menuselection:`Tools` menu, which will trigger an update whenever the index is updated.

+The ";" is required, and "synopsis" is not case sensitive.
+If it is correctly formatted, the syntax highlighter will indicate this by altering the colour of the word.

+.. note::
+   Only one comment can be flagged as a synopsis comment for each heading.
