Defining navigation is currently a bit of a hurdle to take. Ideally we should be able to:
1. Define an overall app navigation structure, combining multiple options such as:
* Bottom bar (horizontal) navigation icons
* Top bar navigation items
* Back/return items
* Hamburger menu
2. Apply the best option for the screen you are working on.
In a way this means that you are also able to divide a screen into multiple sections (header/footer/middle section/...), which is a great way to structure the work. Finally, this will drastically reduce the work to copy-paste-configure-position the navigation structure on each screen!
