It could be nice to see the arrangement of a song on the confidence monitor so the band knows where the song is going.
A potentially even cooler implementation of this would be bolding/enlarging the part of the song/arrangement that the slide currently showing is part of.
For example, B1 would be larger in font size by 2 pts or so and bolded to signify that the confidence monitor song slide is part of Bridge 1 (B1). The bolded/enlarged arrangement section would dynamically change as the slides operator moved from one section of the song to the next.
