adding an index for each Hymnal would be a beneficial. I know when we were Christmas Caroling this winter, we were low on books, and some of us resorted to the app, which is great for getting the sheets, but it was harder to know if the numbers we were calling were from the correct hymnal. Being able to search by a certain hymnal would be beneficial. This could be as simple as adding radio buttons at the top that would sort the hymns by selected Hymnal.
