It seems that the update to 19.4 moved the navigation tabs from a horizontal layout (header) above the machine information window to a vertical layout, located to the left of the machine information window. This layout is jarring and breaks what was otherwise a very good layout. Can you please revert the navigation tabs to their previous horizontal position or, at the very least, provide an option for end users to toggle the location back to the original position? It honestly looks like a programming bug.
