I want to have my sheet music and BH lyrics page side by side on my tablet in landscape, rather than having to flick between them all the time. Is this possible?
No, but if you have a second tablet, you can set that up to screen share from the main tablet, and set Settings > General > External Display > Content to Doc +1 on the main tablet and then the main tablet will show the first document or lyrics and the second tablet will show the second document or lyrics.
Thanks Arlo, that's useful. It would be great feature to have though because I often only need the first couple of lines of sheet music to get me going, before switching to lyrics!
In that situation you could make a JPEG image showing your first couple lines of sheet music and insert that into the Lyrics field, as shown in step 17 on this page:
