This is very handy feature 👏 It works well except one tiny issue. I have noticed "Change Default Page Zoom…" points to the wrong Settings page.

There are couple of code related comments below. In general, I think it would be beneficial to find delegate/observing patterns instead of notifications.

@SabrinaTardio, I can't compile the latest version. Can you reproduce it?
