Right now, when you review a Due passage and you click the Line Up button in the bottom right, it reveals the verse one paragraph at a time. This works well in poetic books (Psalms, prophets, etc.) where there are line breaks after almost every clause, but in narrative books a single "line" can be many sentences long. I like to use this feature to progressively reveal a passage as I recite it, since this can be more time-efficient than recording the whole passage with the microphone button and then listening back to it, but if the passage has no line breaks, the Line Up button just reveals the entire thing at once, which defeats the purpose.
I think clicking the Line Up and Next Line buttons should treat punctuation marks like periods, commas, parentheses as delimiters in addition to line breaks; this way, the feature would work the same in poetic contexts while breaking up narrative passages more granularly.
