Looking at the list <http://lilypond.org/doc/v2.18/Documentation/internals/graphical-object-interfaces>, I don’t see a "measure-centred-interface" or something obviously equivalent. So what I meant was: can/should such an interface be created [i.e., "added to that list"], and then the appropriate grob types be made to have that interface as part of their makeup? Of course, it’s quite possible that everything that’s required to do what we’re talking about (i.e., measure-centering MMRs, NoteColumns, text spanners, percent repeats, over-staff scripts, etc.) is already present in another interface (or combination of interfaces), so creating a whole new interface is unnecessary. That’s what I’m trying to get information about.
