Sometimes we may fail to convey to the user of things changing on the screen in a perceivable way. Toasts and similar should be announced. We may want to make clear that some content on the screen changed. Or we might want to update on progress.
Anything representing a heading in the app should have the header trait. It allows for a faster way of exploring a screen and jumping to the part of the app you are interested in. Screens should also start with a header.
