I realize that this issue has been brought up before, but I'd like to revive it.
As a musician who deals often in Renaissance music, as well as a composer who writes in what I call a "Neo-Renaissance" style, I would like an easier method of inputting musica ficta: small accidentals located above the notehead. I realize that this can be done by reducing the size, then changing the x- and y- offsets (the y- offset differs in each instance), but a method that's done with one operation rather than three would be nice. Has anyone worked on a plug-in to accomplish this? (I know nothing about coding, otherwise I would myself.)
