Hi Alexander,
Thanks for this. But I suppose I was not really referring to the highly specific issues in the other thread (or I would have kept in that thread). I would still like to be able to start a new score with no break, for example in books of say, harpsichord music with lots of small, short movements, where the systems would be the same proportions but the piece is new.
Although I am fluent in Scheme, I have no idea at all what area of lilypond to start digging in to address such.
Andrew
