I would like to have some kind of option into context menu called: "Show All Assigned Instruments".

By this feature you get additional information easily. For example artist, who is playing, type, feel, average tempo genre, memo. And just all selected instruments, no more and no less.

Compare what track window tells you about the instruments and player
"BB RealGuitar 510".

When making a hybrid style by combining all kind of suitable instruments it is very interesting to know what is the final band playing. Are you using "even" and "swing" feel players? That was a common error in 50's/60's, when rock was young.

Thank you for your time
