Phrasing Lines (Different from Slurs)
It is almost exactly the same as slurs, only they are positioned above the staff. Muse Score's slurs can actually be adjusted to look like phrasing lines, of course, but this requires extra work on the part of the composer, since when the slur markings are attached to a note, they snap to a position inside the staff by default, requiring them to be manually adjusted to a position outside the staff, as would be appropriate to a phrasing line. Also, the ability to place a phrasing line over a whole highlighted passage, so that it automatically anchored itself to the first and last note of the phrase, would be valuable in my estimation.
Thank you again for your consideration.
