Hi Hans, About 1: The cross-staff Arpeggio appears to be handled as part of the Staff Group, not of the Staves. Thus add \override Arpeggio.font-size = #-3 to the PianoStaff. As this will also affect the staves within you need to specify \override Arpeggio.font-size = #0 for these.
For the SpanBars: If you open scm/bar-line.scm you can find the function
(define (make-dashed-bar-line grob extent) [etc]
And replace the line
(staff-space (ly:staff-symbol-staff-space grob))
By
(grob-staff-space (ly:grob-property grob 'staff-space))
(staff-space
(if (null? grob-staff-space) (ly:staff-symbol-staff-space grob)
grob-staff-space))
This would then allow you to do
\override BarLine.staff-space = #1
Of course it would be much better to revise the whole span bar routine to
specify such values from the SpanBar grob instead (so we’d be able to do
\override SpanBar.staff-space = #1
instead).
For 3) I think it would be good if you could provide some code.
Cheers,
Valentin
