As I mentioned in another thread, I'm working on a hymnal/psalter project and ideally would like to justify both the left and right edges of each line of lyrics. I'm willing to settle for the left edge, if the right edge is too cumbersome to do. I manually right-justified the last syllables on one psalm, but hard right justification doesn't look good since it puts the right edge under the notehead. My concern with fractional right justification is that if it is proportional (setting the alignment to #0.5 justifies halfway between center and right, relative to the width of the syllable), I'll still end up with a ragged line.
Thanks,
Carl
