+<section><title>Simplify All Tracks</title>
+<para>
+This opens dialog to request the number of points each track will be simplified using <application>GPSBabel</application>. The result is put into a new layer. The simplification method removes points considered to be in a 'near straight line', thus reducing the number of points and attempting to keep the most important turning points.

+<section><title>Remove Duplicate Waypoints</title>
+<para>
+Remove Duplicate Waypoints - fairly self explainatory, with the results created in a new layer.
+</para>
+<note>
+<para>
+However it only considers a precise position (waypoints only 1 metre away from each other are considered different) and also doesn't consider if the waypoints have different comments, symbols or images.

+<itemizedlist>
+<listitem><para>Waypoints Inside This</para></listitem>
+<listitem><para>Waypoints Outside This</para></listitem>
+</itemizedlist>
