Congrats on having sight now, and for getting past our momentary collective immaturity and insensitivity to a valid question.
I can tell you that there was an amazing amount of thought and work that they put into the complete redesign of the user interface between 8.5.3 and X1. There are soooo many functions to cram on to a screen that every pixel of real estate must have been agonized over during all of that.
All in all, the X1 changes opened up Sonar to a much wider market, and have continued with X2 - which got a 9 out of 10 in I think Music Magazine in their Dec issue.
Submit it as a feature request, clearly by having underlined shortcut keys within each of those Track Pane tabs (Views, Tracks, Clips, etc.) that they mean for people to be able to skip the mouse once in there, maybe they just didn't realize that there was no non-mousey way to get to those drop downs.
