Condensed vertical note view toggle
Show only rows with notes that are recorded. There is too much of scrolling with the ^V knob
Especially good when notes in a track span in 3 octaves. Even If have 16 various notes recorded I only scroll two screens. The color is enough as indicator of distance between notes.
If that does not work then we need a pentatonic scales option so that 8 rows would do almost span two octaves. While on it hide the black notes in the scale keyboard view so I only play good notes.
