Why are the layout options the same for both page view and to galley view? It seems these want to be independent since galley view is mainly a screen size presentation for data entry and page view is for printing and the two are likely vastly different in size/shape depending on the score.
I find that adjusting a score with a large number of instruments for page view and having that apply to galley view makes it harder to enter music as it requires zooming in further to be able to place items correctly.
Maybe I’m missing something, but it seems more intuitive if the views had independent layout options.
