I can’t agree with this at all. It’s effortless to insert a Frame Break where you need it, and you don’t have to worry about ‘consequences’ of moving a system to a new page, as you would in Finale.
I used to spend half my life moving staves and systems manually in Finale; and I do next to nothing in Dorico by comparison.
Dorico is still young – less than eight years old – and there is still a LOT on the To Do list. Fully automatic page-turns with AI to consider where they should go would be nice, but it doesn’t stop us from creating the pages ourselves; whereas there are still some things that can’t be done at all.
