I love Dorico SE as an on-the-go, sketch ideas and project reader (I have the Pro version). One feature that would be incredible for composers that collaborate with musicians and ensembles is leaving the comments feature accessible after limit of players is reached. Sending music over to performers across the globe and allowing them to ask questions and make suggestions would be invaluable. I will already be encouraging others to get their copy of SE to preview my works. Of course they can send an email with comments, but comments on the score? Would be so good. Just a thought!
