Allow merge rests to be a global option
In version 3.5 you can now use staff/part properties to "merge matching rests" on a staff by staff basis. This is fine for a couple of instruments. It would be nice to have this as a global option (style or preference) for those of us who need it on a dozen or more staves. It would be OK to have to do this for every score, but it would be better if we could make it a permanent option if we like.
