PDF & Ebook Reader App "iOS 15 Style"

I personally found Safari's floating tab bar from the iOS 15 betas really interesting. They ended ditching it because of it not being very usable as browser navigation, but I felt like it would be great in a much simpler app, like a PDF or an Ebook reader. It doesn't take up much space and allows the user to immerse him or herself in the content, whilst providing the necessary tools to create a great experience. As an example of the bar's functionality, I added the "page formatting" screen, accessible by tapping a button.

It was designed in Figma and uses Apple's provided fonts and icons for iOS. Mockup courtesy of "smrkv".
