I notice in the software and the website there doesn't seem to be an option to display the complete family tree.
This would be an excellent option as it can be confusing when selecting home and finding some parts of the tree are not visible, so unless we know it's there, we may not find it.
Printing a chart with the complete family tree would be another thing i'd love to see available.
There is a way to view the entire tree in one shot, we call it the "All-in-one" chart.
Go to the Family tree tab and click the Print chart link. Select the first chart type called "All-in-one" and generate the chart. You will get a PDF file that contains a chart of all the people in your tree.
