Use case or problem
When I’m reading a file, I don’t actively need the navigation elements that take up a lot of screen real estate.
Proposed solution
Add toggle for native iOS behavior for bottom tab bar to slide out when you start scrolling down and reappear when you start scrolling back up. Bonus would be to also minimize the top title bar as well (example: Safari browser when tab layout is set to “Single Tab” in iOS Settings). It’s so much nicer for reading articles and long documents.
