1: full screen faders(with some narrow overview of project)
2:fader cap colors as in cubase 7 by track type
2.1 : option to sync cubase mixer view(hidden on MC won't show in Ic pro also)
3:channel editor to control EQ, sends,gain, and Filters
4:having write,read,monitor,and record buttons view all together.
