playback pointer/bar, color of notes during playback

I noticed that during playback the vertical travelling bar of M.3 , that was a pretty large one blue color trasparente, has been replaced by a line, blu, very thin, like it is in Finale or Harmony Assistant. Is it possible to go back to the v.3 style, i.e. large vertical bar blu transparent?
Further, Harmony Assistant when in playback the note played is also made red, which is interesting to help my singer when they learn. Is it possible to implement this feature also in M4? Thanks
