Dave, you have to remember, the primary function of Band In A Box is to create automatic accompaniment using only chord symbols you input in a matter of minutes. The printing part is just a bonus.

Having said that, I do also sometimes wish for better print options, better 1st and 2nd endings, better repeats, more control, etc. But all that adds up to Sibelius or Finale. SO, my next best wish is for Band In A Box Midi file exports to contain the chord symbol information as well as the notes so it can all be imported into Sibelius or Finale.
