Hello,
It is obvious that people buy Notion for arranging Classical style. Meanwhile, Mordent is very common in lots of Classical and Baroque compositions. There are tons of examples out there, like the beginning of J. S. Bach's Sarabande from the fifth French Suite, and the popular Toccata and Fugue in D Minor, that start with a Mordent. Please include this ornament in your upcoming update.
Thanks!
