Audiobooks in the music app: they've gotten rid of the chapter list view, so now if you want to jump to a specific chapter/point in the book you have to use a 1 1/2 -inch scrub bar with your meaty ape-descended finger to precisely navigate a 14-hour novel.

Check to see if scrubbing is like it was in iOS6 videos... as you are scrubbing slide your finger down screen (sorta at an angle... but mostly down) and you will get finer increment scrubbing rates.
