this is a suggestion by Urs from a user list thread on 2018-08-30: for
putting together scores of four-hand music with the typical primo

only odd or only even pages, with according page numbers and margins
(in case of twosided = ##t).
Just to clarify, is this request strictly about page numbering and
margins (something I believe LilyPond already supports albeit via
manual* configuration), or does it also encompass the automatic
synchronization between the primo and secondo parts at each page break
(also something that requires manual** intervention to achieve at the
moment)?
* Each part's margins can be customized uniquely to achieve the
desired mirroring, and the page numbering needs only a little
arithmetic to show up as odd-only or even-only.
** Providing things do not align by chance, adding explicit \pageBreak
commands would ensure that page turns happen at the same moment.
This is not about automatic synchronization. That’s of course a far
longer shot, and there’s already an issue for it (don’t want to search
it right now).
If adding a simple switch for odd-only/even-only is only syntactic sugar
of sorts for functionality that with some effort is already available,
that’s all the better, then this is only about designing the interface.
Best, Simon
