More specifically, hairpin styles don’t reflect in other layouts. I have an opinion.
I think the confusion comes from the fact that hairpin style property is accessible in both Write and Engrave modes. (“type” and “gradual type” property as well)
I understand that, with the Dorico’s very basic concept, something you “Write” effects in all layouts (globally). Something you “Engrave” effects only in the layout you’re engraving (locally).
IMO, different hairpin styles would indicate musically different things. not just different appearance, so I think this property more naturally belongs to Write mode, and choice/change of this property should be reflected in all the layouts.
I know the current way enables us to have different values of the properties in each layout. But we would want different value only in very rare cases. We need a way to specify only when the choice/change is local (only in specific layout). Maybe “layout specific property” switch on the left to show the “Write-mode properties” in Engrave mode is a logical way? Anyway, I hope changing this kind of properties will effect in all the layouts since it is different not just in appearance, but also in meaning musically. Manually changing the same property throughout all the layouts that contain the object is not very elegant…
I think this type of confusion is not only with hairpins but also with other kinds of objects. Lots of properties are accessible in both Write and Engrave modes. I guess it should be about the balance between practicality and simplicity/logicality. I’m optimistic and hoping these confusions will be cleared up by the clever team with the simple/logical and elegant concept of Dorico.
