I understand that the file name is just taken from the Name field in the Instrument section.
As a professional piano tuner I would enter the customer name in the Name. field. But then it would quickly become a mess as I often have customers with the same last name or lets say the theatre or University with several instruments.
It would therefore be nice if the file name would be automatically created from (e.g.) %Name%Instrument%Serialnumber. Maybe this could even be customisable in the settings. What do you think?
