Name of keys and labels in German notation, Fingering feature

Hi,

I am an Austrian piano teacher and today, I subscribed for SeeMusic. It´s a fantastic app, but for German countries, it would be great to be able to change the name of keys/notes to German system (CDEFGAH). A fingering-option for notes and/or keys would also be very helpful, especially for my young students.

Thank you for this great app!

Bernd
