Hey @nevillewhitemusic,
Thank you for your detailed explanation!
I just released a new beta that both fixes the behavior of the previous song button on the setlist page and adds a new option that allows you to always skip to the previous song instead of first jumping to the beginning of the first song.
You can find it here: AbleSet 2.8.0-beta.11
Let me know if this works for you! I’m looking forward to your feedback
