Sibelius and Finale formats
In future releases of MuseScore, I reccomend a Sibelius and Finale file importer for people who own those products and wish for clients (or students, in an educational settting) to be able to view, and possibly edit/revise scores with MuseScore. That's the only improvement I could possibly suggest. Thank you for keeping this program free, and this truly is a wonderful music notation program.
Wishing the best,
