Thank you for the 27 update.
I work a lot in Finale, and sharing music is not a big part. I use PDF-files and mp3-files.
I think would have been useful are the ability to import more VST synths so that I can work with high-quality sounds with, for example, kontakt. It has also been nice to have video. The Workflow is important for me, and I think Finale is getting better.
Scanning or importing pdf files I understand can be problematic with rights.
