When there's a long console output, navigation becomes difficult, because the user has to scroll all the way up before being able to use the navigation bar or see the other steps. (See the attached image.)

I would recommend, to improve usability one of the following solutions:

• Always show the top navigation bar (display it fixed at the top)
• Limit the height of the console output, and add an inner scrollbar

An alternative would also be to show an smaller version of the top navigation bar when the user starts to scroll down.
