Good ideas

Have you got any 'good ideas' which would help others in their use of Power Music?
For example, during the Kingsway conference someone mentioned that they were going to get a small monitor set up for the projectionists at the back so they could see what the musicians could see.
Our immediate reaction was 'What a good idea!'
Not only can the musicians know exactly which song to play because it is on their screen, but also the 'lyrics' controller can see if the band have skipped a song or two and can easily bring up the correct one on the projector.
