*Ghost* staves - i.e. Dynamically linked staves within the score
It strikes me that it might be useful to have a new feature whereby we could assign any stave to be a *Ghost* stave. In other words, it would then show the contents, and be dynamically linked to, any another assigned stave in the same score (but with an optionally different name, instrument, clef etc.).
This would be be similar to the dynamic linking between score/parts, but *within* the score itself.
It would be useful in cases where one or more instruments play exactly the same thing - i.e. it would save having to make *real* copies on every stave, thus (presumably) reducing file size where this occurs a lot. More importantly though, all staves containing the melody (for example) would update automatically whenever just one part is edited.
Perhaps a *ghost* stave could be also assigned multiple staves, to create a sort of dynamically linked "implode" function (or to show a dynamically-linked short score alongside a full score)?
