Parentheses around optional/ghost notes look horrible
Whenever I add parentheses around a note (from the ‘Accidentals’ or ‘Noteheads’ palette), they look ugly as a mud fence:
— They are too close to the note.
— They seem too stretched vertically, overlapping with other notes from the chord.
— They overlap with the flags of grace notes (semiquavers and shorter).
Compare the nice typeset examples on the left with the Musescore output in the attached image. In all these examples, the engraved version is more rounded, more lightweight (there is more contrast between the end and middle thickness), shorter in height, and further away from the note in question.
Can we improve the quality of ghost note appearance?
