Version 4.6 has been submitted to the app store. It should be available for download in several days.
1. Tested with macOS 10.14.2 Mojave.
2. Fixed possible playback problem with very long audiobooks e.g. no sound.
3. Book volumes are now given same name as book title instead of “Volume 1” etc.
4. For users using the iTunes option “Keep iTunes Media folder organized”, fixed possible issue with multiple volume audiobooks being out of order during playback.
5. Made it slightly faster 🙂
