I'm trying to figure out how the layout and positioning system works. Lilypond is able to move some of these outside-staff objects vertically to avoid them overlapping, though I'd rather some items get pushed horizontally rather than stack and take up more vertical space. I know I can use outside-staff-priority to control relative vertical positioning of these objects, but this doesn't seem to help with vertical positioning. For example, I'd like measure 4 to be wide enough to accomodate the "Allegro non troppo" tempo marking without it being pushed above the volta bracket, the volta bracket should also be shortened to make room for rehearsal letter B, and the "Trio" section label should be pushed to the right of rehearsal letter C instead of below it. Is it possible to do this in Lilypond?
