Saving songs with backgrounds

Is it possible to save song lyrics with backgrounds so I don't have to work them from scratch each time?

No, Worship Tools Presenter doesn't remember what background you used previously. But if you keep track (I have a spreadsheet with every song, the background I use for each one, and other info), it's quick to give it the same background the next time you use it. When you go to Your Media Library, type the file name for the background you want into the Name filter, and the desired background will be shown. Your other formatting is kept, so that's enough to restore the song to how you had it the last time. You don't have to work the songs from scratch each time.
