The default element that appears on every screen is the Screen settings. The purpose of the screen settings is to show the swipe (small dots) and the number of dots depends on the number of screens. You will only be able to see the dots once you have more than one screen.
You are able to personalize the dots by choosing the color and selected color. As well as the location on the screen.
Another capability in the screen settings is to be able to select a Canvas color. There are three options to choose from under the 'Canvas color': Color, Transparent, and Gradient. This is useful especially if you do not want to have an image covering the entire screen.
If you do not want the swipe dots in the screen you are able to hide them. Click on to hide the indicator (it should appear like this ).
