Jim,
in minimalistic view, what you call a "time line" (under transport buttons) was done in a manner of navigator. Unfortunately it was poorly executed and is pretty much useless as navigator or timeline on medium size project of about 70 bars or more. Don't confuse with a Big button view (the one I presume you are using), where the timeline actually serves a purpose. What I proposed is do a true Slider Navigator instead of "whatever you want to call it" item below transport buttons in minimalistic view and do a full length time line across the screen (like one in Big button view). Does that make sense?
