Both these features worked properly in iOS 6.
We have invested a lot in audiobooks on the iPhone and the removal/alteration of these features has diminished the value of our investment as well as the value of the phone. Put these features back in the next iOS release, specifically:
- Restore chapter display/navigation for commercial and standards based homemade audiobooks.
- Make the time scrubber display and use the time in the chapter not the time in the data segment.
