This release adds the experimental option to show song melodies. Enable this option under Advanced Settings. A melody button will appear for every song having a melody.
Further, you can now long press a song to directly select the verses needed to be displayed or added to the song list.
Songs with similar names will display more details to tell them from each other.
And some more minor fixes/improvements.
