In order to be able to use different fonts for left- and right-hand fingerings, I have created the right-hand fingerings as “playing techniques”. And I have defined all the missing barre settings with continuation lines as playing techniques too.
If I add the fingerings before the barres, the barres will not show continuations lines (even if they are defined for all variants). I can not even add the lines manually using the property panel.
I guess it isn’t the way it should work. Of course, this is workarounds, but continuation lines should work no matter when they are added in the workflow.
