For easy navigation all applications are divided into themes. Each theme has its own unique set of functions. For example: the "Online store" theme has shopping cart, required for the purchase of goods, while the "Restaurant" theme has the function of table reservation. If you do not need some of the functions, you can always enable or disable them as and when necessary.
Having selected mobile application, you must select a pattern which will form the basis of your application. View of themes, and templates is available to all users, but you need to sign up or sign in to select a pattern. If you are already signed in then after selecting a pattern, you will get to the content page, and application settings.
