Really impressive update with so great new features!
Congratulations for innovative ideas.
One question: is anything new about linking/unlinking items properties in score and parts?
Not yet, no.
I hope this will be added in a near future ^^
Oh, c’est dommage 
Thank you for your information.
Yes, we know that this is a big impediment to the efficient preparation of parts. We will tackle it as soon as it is practical. As I explained in my blog post today, everything we do has an opportunity cost associated with it: choosing to do something means actively choosing not to do something else. But we know the properties workflow issues are real and we will solve them.
