Currently, if you compose a song, you have zero way of knowing what exactly you composed without playing the entirety of the song using the =next commands. On top of this the %prounoun coding is lost entirely.
I think it would be nice if a musician could actually be shown the coding and the segments and what is played each time you hit =next so that they can refresh themselves on their own songs and be able to pinpoint where exactly a song may be failing by typo.
