Hello,
It would be great if using the R command on a slur would repeat with a new slur of the same length after the first one. I can imagine lots of places where this would save time.
As it is now, the slur repeats starting from the last note of the previous slur. Not so useful I think.
Even better, of course, would be an extended slur command where you can make a selection and apply lots of slurs at once by beats or number of notes.
