I can't recall if I asked for this before, or just larger faders, but Having the ability to stretch (or select between 2-3 different fader lengths) would be divine. The fader movements we still have today are quite small.
I just watched the new Studio One 3 promo video, which is chock full of things that people will rave about, but the only thing that I REALLY liked about it was the stretchable faders. That was SO cool!!
I think if Sonar had merely a selectable fader length (like from 50mm, 100mm, to 150mm) and have the meters match that length, this would be killer!!
