I would like to ask for a way, to manually adjust the Gap measurement for two or more staves/systems at once (Staff Spacing).
It also would be great to do some maths to them, e.g. “+1.5”.
And an option, to adjust the staff spacing of the last page to match up with the penultimate page, if the last page is below xy%, would be great for part editing.
(I know about the method to drag the music frame of the last page to match pages, but it would like to avoid red triangles as much as I can.)
