We use 5 different songbooks, it would be very convenient for the musicians, to be able to search for the book and number of a Song.Sometimes I can't find a song by its titel. Titles don't always correspond fully to the text, at least in german. Some people like to sing from the book as they want to read the music. It would be very helpful, if it was possible to have as a first slide of a song a slide containing the title and the songbook with the song number
