I’m not sure if there’s already a way to do this, but I’d love to see instrument filters in page view mode. Unless I’m mistaken, it’s only possible to filter instruments in Galley view, but it would be nice to be able to filter them in Page view. (especially so you could export sections as their own pdfs without having to use external tools).
Welcome to the forum @SamCPetitt
Indeed it’s possible only in Galley View – hiding staves would change the layout considerably .
But you are free to create multiple new – score and part – layouts with the instruments you want.
