To navigate around the app:
1) Pull the screen down with your finger
2) Tap the Menu button at the top left of the screen that looks like three horizontal lines
3) This allows you to view the separate sections and browse all the available content and features
Within this screen you will see the Home button in the top left corner, which will take you back to all of the editions available to download.
Tapping the symbol in the top-right corner resembling three vertical squares and an arrow allows you to change the order these sections appear. You can do this by holding down on the three vertical lines next to each section and drag them up or down to personalise your edition.
