A new option when viewing the charts gives you the ability to either create a route or to simply mark specific points on top of the images. Both of these options will create a list of the marked locations at the bottom of the page, giving you the ability to easily print the chart and locations on a single page. Both options are similar - the main difference being that creating a route will include the distance and bearing between points, and will draw the route with lines on the chart.
