As a user you have serveral options to change the default behavior of the screens.
In the implementation of the “button that opens a view” you can set behaviors such as “ close when parent closes”.
There are also two close buttons available:
You can change the size of the buttons by the scale factor. And if you want to have other symbols you can clone the buttons and choose other images.
To create your own design, just clone our button and replace the picture with another of your own choosing
You must add these two buttons as “Drawing” on the view list.
Also: in your project, you can define behaviors of your “start screen”. An example is "non-closeable".
