Content Settings
Content Settings will cause the cover of titles to be blurred and have a letter on them.

Rating Indicators
There are three letters that may appear on the blurred covers:
- A for Adult
- M for Mature
- U for Unknown

App Configuration
Once enabled on your device, two new sections for content settings will appear in the Paperback app.
