Cool arrow idea

[Randomllyin]

Hear me out
What if
You could set BF to have 4 keys
And then give the opponent 16 notes
and then put 8 of the opponent notes on the bottom
Kinda like this (Default arrows are BF)

I put BF's arrows on the right like that because the original mockup was gonna have the arrows going right

honestly you could probably just do that with modcharting if you were good enough at it but it would be tough
