Always be able to apply any FX PRE/POST-FADER (on cue as well)

So this would be very useful cause often times I wanna tweak the effect in my left ear before I push it out to the audience.

I get the argument that some effects are post-fader and others are pre-fader, but honestly that's rubbish, they should all be both PRE and POST.

When you cue with the fader down everything you apply, including the effects of course,  should only go to the left ear, later you decide what to do with it.

Thank you
