some practical small but useful issues that I noticed:
1. audio playback (for example OT Hebrew Audio Module) stops when the screen is locked. it would be nice to have the playback on all the time like other apps do.
2. additional thing: auto follow-on to next chapters without need to play each one separately
3. last not least: it would be very very useful to have verses history synced between devices in order to access my last searches or studied verses on Mac on my iPhone or iPad.
all the best.
