hide cautionary clefs, keys and time signature

as “chrisg0619” and others mentioned. There are people, how definitly do need the hiding of cautionary key and time signatures.
Working with lots of snippets of music (one up to four bars) for my worksheets and solfeggio papers, is perhaps not the way Dorico is meant for by the software-designers, but the need is here. Sometimes I work with 200 and more examples, so this would mean 200 flows. That’s not manageable anymore and I wouldn’t find my way around all those flows. So I could start a new piece every tenth flow and my paper is torn apart in different files.
Hopefully you – Daniel – see and understand at least the need for this wish!
