One thing that I've found with adjusting the verse split points in the service list is that the adjustments are lost when another song is loaded.
It would be nice if these adjustments were saved with the service list so that you can set-up all songs to display as required before the service, or even save them, close ZW and come back to it at a later point and the split point adjustments still be in place.
This is not essential, but I feel like it would make a positive difference to the usability of this feature.
Cheers,
Chris
