It would be nice to be able to clone a staff. Not just copy the contents to a new staff, but copy the properties as well, with a single command. I can see it appearing in either the "staff" drop-down menu or the "tools" drop-down - either one would be a good home for it. Potential uses include creating staff layers, creating staves with different music but the same instrument (i.e., string quartets, vocal duets, choirs, flute trios, etc.), creating separate audio and printed staff systems, making a new score without using a template, and probably others.
