Does iBooks have a white-text-on-black-background option, the kind that makes reading in bed spouse-friendly?
Sadly, no, although you can fake it by opening the Settings app, tapping on General, then selecting Accessibility, and turning on “White on Black.” You can even set that features as a short-cut when you click three times on the home button. But that feature inverts the iPad’s entire interface, which is far from elegant. The good news is, iBooks does allow you to control the iPad’s backlight level directly from within the app. But we agree that a white-on-black option would be a good idea and we hope it’s added to iBooks.
