I really can't count how many times I had to to that in so many scores. And there's no way to do that automagically. Really no way. Otherwise I would not have asked what I'm asking. Then I'm forced to use the extra-offset property for now. Hope that someone could solve this issue. I'm sure there's a way for doing that, without changing the code and whole Lilypond would have a great benefit from it. I’m sure that within the current code base there is no way to solve this issue in the means you have proposed. When the Y-offset property of a grob is an unpure-pure-container, final positioning is done *after* \offset is applied to the unpure-pure-container value. And then collision avoidance is applied, along with “automagic” placement. So the only way to solve this problem with the current code base is to use extra-offset. But then you also get to do your own collision avoidance. I’m sorry, but I think this is the current state of LilyPond’s placement algorithms. And that’s why I prefer to find ways to tweak the placement algorithms, as opposed to tweaking the grobs. Thanks, Carl
