How to shift space between staves?
How do you increase the vertical spacing between grouped staves, but decrease it between separate staff groups?
In the attached file, I have staves for standard notation and tabs that don't have enough space, so the bottom most notes are overlapping with the top-most tabs.
However, the space between each group is massive. How can I shrink that wasted space, and use it to give some extra space between my standard notation and tabs?
