Showing arpeggio signs before/after grace notes

You can show arpeggio signs before/after grace notes individually. By default, arpeggio signs are positioned immediately to the left of the notes to which they apply, and so are positioned between normal notes and grace notes.

1. Select the arpeggio signs you want to show before grace notes. You can do this in Write mode and Engrave mode.
2. In the Properties panel, activate/deactivate Arpeggio before grace notes in the Arpeggios group.

Result

The selected arpeggio signs are shown before grace notes when the property is activated, and after grace notes when the property is deactivated.
