In the Staff Spacing tool, by dragging different handles you can choose whether to move only one staff or an entire poly-staff system, while keeping its internal spacing unaffected. However, when holding Alt/Opt and dragging a system handle, it will keep that particular system’s internal spacing the same but scale all the individual staves in other systems, which to me feels inconsistent.
Also, while I’m here:
- Could we have Alt/Opt-drag also proportionately expand staff/system spacing in the other direction? Perhaps with a second modifier key, and when you hold them both it does both the contracting and expanding. (I know this has been requested before.)
- It would be nice to have this proportional contraction/expansion also when using the keyboard instead of only when dragging with the mouse. Although that would be a mess with the modifier keys because both Alt/Opt and Shift are already occupied in that case…
