That's great, thanks for pointing out the Smart Buttons link to external file.  I'd missed that new feature.

The only very minor issue I'd flag up is that on Android, linking to and opening an mscz file adds that file to MuseScore Songbook's library first, then opens it in Songbook.  Since all these files are already in Songbook's library, this creates a duplicate library entry.  But all that said, it's simply to delete that new dupe - far easier than the previous 'clickflow.'

So thanks Mike - it's a winner, another one.
