Good content but 90s presentation

The content of this app is outstanding, no doubt.

But its the same content as in the iPhone version. This should mean that it can use the full screen on your Mac, but the display of the app is hard coded to 800 pixels wide and cannot be changed. This means on any modern Macbook only half the screen is being used. This limitation makes the app feel like an old style program rather than a modern, native Mac app. AND it makes it hard to read what is essentially an interactive book.
