Audiobook app features

Hi,

How about you integrate the features from the audiobook app into the music app now that it won't make a comeback. I need bookmarks, being able to mark books as read/listened too, start a list on what to listen to next. 

Listening to audiobooks via the music app is tedious, especially if you'd like to switch it up with music from time to time. I have to like the chapter, then find the heart in the list again (books 400+ chapters make this quite the effort!!) And the unlike the songs/chapters again so they're not part of my flow..

Pretty please!
