Are there any tentative plans to add this feature on Android? On the desktop I have renamed many of my commentaries to include the series name in the title so that when I run the Passage Guide and have multiple commentaries called "the pastoral epistles," for example, I can see which set each volume belongs to. It would be nice to have this feature available on Android as well if possible. It might also help me to identify which commentaries are already downloaded on my device and which ones will potentially require mobile data to open. Thanks for the consideration.
