We should allow students to enjoy as much as screen as possible and display only the bottom menu (with the navigation actions) when required.
For example, in a quiz activity or lesson, it should not be displayed until the user completes it.
Same for the book, it should be only displayed when the user reaches the end of the book.
For SCORM and H5P we should evaluate what to do, maybe we could display it collapsed and allow the user to expand it.
For other activities, we might make more obvious the action button MOBILE-3149
