It would be very helpful to have the possibility to define different font attributes (size, etc...) between score and parts, for expressions, text blocks (at least). Similar to what is possible for measure attributes. And without having to resort to time-consuming workarounds (special expression categories for score and for parts, duplicating/hiding text blocks, fixed size experiments ...)

This request has been made for years (see link below) and I see the problem repeatedly evoked on the forums.
