I may have posted about a similar issue a few years ago. I like to print my music with standard notation measures and guitar tab notation (six lines with numerical tabs) below the standard notation.

BAIB does this fine, but has preset spacing between the standard and tab notation lines that is too wide. The result is that a good 50% of the paper is taken up with blank space between the notation and tabs, resulting in a song using 3 or 4 sheets of paper instead of 2.

I have looked at every setting and have not seen a way of modifying this spacing. Can someone let me know if Ive just missed it, and, if not, I'd sure like to see this added to the notation settings.
