When using chords, you may want to put note cuts after each note to stop the chord from ringing. You've got some ways of doing this.

1. Manually put a note cut on each row by pressing the note cut key, clicking on the next row, pressing the note cut button and so on.

2. Toggle "Record note off" and release the note before the shift key (releasing the shift key before the note only creates one note cut).

If you wanted to have let's say one chord every 2 rows with a note cut in between, you can't do that with the second method alone. You would have to set Row Spacing to 1, input the chord, release the note, release shift, press down, repeat. Note also that this doesn't work with "Repeat notes on hold" (unless you're a ninja)

My preferred method of working with regular notes is to first input all of the notes with a certain row spacing, then selecting the row in between the notes and pressing § to create a note cut which also jumps down to the next location due to the row spacing.

My proposed feature is a chord cut feature (on shift+§) that does just this but on several rows at the same time, depending on the rows created by the last chord.

Granted, this is more a convenience thing, I could always just use the first method and then copy paste the note cuts everywhere. :)
