Application are either "tabbed" or "non-tabbed" and not both. Tabbed layouts use up to 5 home screens, one for each tab and are well suited for apps that have lots of content and features. Non-tabbed layouts use one home screen and are best for apps that have limited content and features.

The apps configuration file includes a list of tabs. This list is required but may be empty. The apps configuration file also includes a list of screens, menus, and features. If the app uses a tabbed layout, each BT_tab item describes how that tab is configured. If the app's tab array is empty, the first screen in the list of screens becomes the home screen.
