A useful tool to reset the following properties:

• Slur contour & positioning
  reshapes existing slurs based on your current contour settings
  now in the separate Modify->Slurs plug-in!

• Hairpin opening width
  changes all hairpins in the selected region

• Make hairpins across system breaks horizontal
  useful for Finale 2000+ because in these versions, hairpins across system breaks can  become diagonal, strange-looking

• Repair smart-shape bits
  (rarely) needed before copy & paste when Finale forgets smart shapes such as hairpins
