To be expected at first! because this aspect of Dorico has capabilities far beyond Finale’s. In this area it’s designed more like a page layout program such as InDesign or Quark. Getting comfortable with page templates is a whole new world for music copyists.
Here’s a link to one of my favorite Dorico success stories on the forum, particularly mentioning streamlined page layout tasks.
I don’t see myself ever doing anything as complex as that opera example. I still find Dorico EXTREMELY confusing. Right now I am dealing with staves writing on top of one another. In Finale you just tell the program how many staves per page and BINGO! It’s done. I am new. I understand. But it is taking me FOREVER to get simple things done. Writing a duet has become a monumental task. I find the menus confusing - thinks to click on the left, thinks to click on the right. “Layout options” is under “library”?? “Flows”, “Frames” ?? I will keep working at it because Finale is going away. But I am not a happy camper. I may check out MuseScore to see if that is more to my liking.
It gets better. Figuring out where things are located and the logic behind it is a key skill initially. At the beginning, pre-manual, it was even more of a challenge; but the folks we rely on for sophisticated advice today are the ones nurtured in that environment.
