Well darn, I came here to make a suggestion for JJ2+ and this is what I see.

Still, I suggest adding the option to choose between Double Jump and Helicopter Ears in the Plus menu. That would be useful for those like me that want to play as Jazz or Lori but still want to Double Jump (and maybe there's someone who wants copter ears on Spaz, who knows?). I don't see how this would affect the Multiplayer experience, except from maybe deceiving your enemies a tiny bit? In rest, Jazz + D.J. = Useless ability, Lori + D.J. = Almost Spaz, Spaz + H.E. = Almost Lori.

Or at least in Single Player, that would be fine too. Yes, I know it's possible to do with AS but I won't take my time to make and apply a script for every single SP level I play.
