Slur parameter copy/paste
Slurs on similar melodic contours on a page should have an identical look. However, it is difficult and time consuming to match the look of two slurs exactly by adjusting with the mouse. It would be very useful to be able to copy the parameters of a particular slur, and apply the setting to a slur at another point in the music. (See for example the opening demo song which has pairs of slurs that should look exactly the same).
