The first group in the Input Panel is the General Input group. Here, you can edit the name and orientation of the street.
You can type any name into the field next to 'Name'. This name will also appear in the title of the Display Window.
You can change the compass orientation of the street by either dragging the slider, or typing in a value (0 - 360 degrees, where 0/360 is North, 90/180 is west/east etc.). This orientation is the direction 'up the page' on the plan, and the direction looking 'away from you' in the cross section. It is used to generate the shadow visualization. (You can adjust the detailed settings for this in the Sun and Shadow)
