I think I have an idea that could help with shaping the music (considering even finale doesn't crescendo or decrescendo) and it could fix the dynamic bugs (an instrument won't play "mf" unless you start at or before the "mf" sign) I think we need a new palette where we would have full control of the volume. There would be lines that go up and down and you could select points for it to crescendo, decrescendo, fp, fmf, and so on. Like pod-casting in garage band.
