A screen represents one single user interface page and can contain several widgets.
When you create a new application, it does not have a screen yet. Add a screen by clicking Add Screen.
You can add more screens at any time by clicking on + New at the screen overview or just click on the + next to the tab of your screens.
A screen is always the start screen. To change the order of the screens, drag it to the required position.
To rename screens change the ID within the properties section on the right. Use the Description field to comment on the screen. This helps to identify the purpose of the screen later.
