ties and slurs
I noticed that the arch between notes behaves differently between ties and slurs:
On ties the ends of the arch point towards the note-heads.
On slurs the ends of the arch point towards the 3/4 end of the note-stems.
On scores supplied to our choristers the various publishers have similar ways of dealing with slurs, but when connecting out of or towards chords, the arch ends point to the intended note-heads (as with ties). I think it would be more consistent if the arch ends mostly point to the note-heads, even if there were no ambiguity. Or are there other reasons as to why on slurs the arch ends point to somewhere along the note-stems?
