Suspend Playback logic for M4B audiobook files

[Tjstan609]

Hello,

I have a suggestion to improve the suspend logic feature, particularly for M4B audiobook files.  Could you add a suspend at bookmark (selected from bookmarks/chapter menu), or suspend at next bookmark (relative to the current playback position)?

Also this seems to be a little bug or lack of option with the current choices, selected time and elapsed time.  Currently, the selected time option uses system clock time for it's reference, and elapsed time option is relative to current position.  I would like to suspend playback at a selected time relative to the start time (00:00:00).

Thank you.
