HOW TO ADD/DELETE A NEW SCREEN
When we create a new app we have only one blank screen displayed.
To add a new screen, just click on the “+” icon, up in the “Screen Tree” side bar.
A window will ask you to enter the screen name.
If you click on the right button of the screen, you can choose among different options:
Open the screen (If you want to edit that screen)
Rename the screen (If you want to change the name)
Clone the screen (if you want to give the same structure of that screen to a new one)
Main Screen (If you want to make this screen the Main screen of the app so that it will be the first to be opened in the app).
Delete (If you want to delete that screen)
