Maybe it's just me, but I am "afraid" of clicking the big Navigate button on main screen, because I am afraid that a wrong target is saved under "Route info" and thus Navigator would send me to the wrong place.
Thus it would be very nice if the big button would display the currently used target - maybe city name or something like that? If this is not possible, I'd like a setting that allows me to receive a conformation message whenever I hit this button, saying something like "Do you really want to drive to XXXX (full target name)?"
