Layout
It is really important to remember that layout can make a huge difference to your app. We have provided two app layouts for you to follow: Core and Full screen.
Core layout

Your app must have
- A header at the top of the screen, which consists of a coloured line, title area and divider
- A content area
- A hidden toolbar with app controls which is revealed by using the bottom edge swipe

Your full screen app must have
- A hidden menu bar which is accessible to the user from the top edge at any time
An app can either launch directly into a full screen layout or contain a full screen view.
