A suggestion to highlight the track names that are currently playing
Just discovered Piano Booster yesterday and I love it already.
I have a suggestion, which is highlighting the active instruments while the song is playing. E.g. if Track 1, 2, 7, 9 are currently playing at this point in time there is either a dot next to the names, or better still it highlights the instrument names with Green color (e.g. the instrument text such as L Piano, Right Piano, Strings, Clarinet will be green if they are currently playing). Any instrument names that are not playing will have their text color remain as black.
I suggested this because it is a useful feature for user to identify what's happening in the MIDI file, and it is less difficult to implement comparing to other features. Hope you can consider, thanks
