Playlist Question

Since the new columns in the Playlist don't save their positions after altering them, does anyone know if there is an .ini file or something that we can disable the columns we don't want? I remember years ago that you could re-arrange the widgets in track view to customize things by going into a file and typing in simple commands. It was documented in the manual how to do it. But it was long ago and maybe that sort of thing is not there anymore. When I use the playlist I like to keep it narrow and to the side and only want to see "the song",and "Delay" settings.
