I think it would be useful to also have the "star" feature on RealTracks and RealDrums as well (ie is rating the instruments)
As well as having the option to have the "stars" from the Styles pass through to the RealTracks and RealDrum lists as well.
as well as the other way around have the "stars" from the instruments pass through to the Styles list.
(all with some indication to see were the stars originate from).
