Hi,
I don't know about fatigue or anything else for that matter, but I would love to be able to color code the Fader Knobs and not be either limited by a few meagre choices or to which Fader I can put certain colours on. Such as with certain strips they are all the same color like the bus strips. I'd like to be able toset the mixer up like a real desk, but coloured fader knobs would do to start with. Put in a feature request.
