navigation in X2.

I recently seen the navigation improvements in cake TV live webinar on X2. I think they are great! First- just want to say thank you cakewalk for the improvements and the webinar.    I was wondering though what happend to navigator view? I know it is still in the program but was wondering why you would not make it so you just drag up and down on it(instead on the timeline) to zoom in and out. So that way I could just click on the part of the project I want to go to and then just drag up and down on the nav view to zoom in and out. Was this ever a thought in anyone's mind at CW? What does anyone else think about this idea?
