I use Galley View a lot and I have the same issue as everyone with vertical spacing often not being enough. I know I can make the spacing bigger but since Galley View spaces staves evenly this brings another set of problems when working with big groups like a 3.3.3.3-4.3.2.1-3perc.timp-pno-hrp-strings orchestra.
Could we have some form of automatic spacing in the future?
