I would love to see the default install screen shot of the home page because I have been working with Roots theme for some time and I remember when the navigation was horizontal and in a responsive mode the three lines (bars).
http://roots-example-project.com/ - better than a screenshot
We removed the Bootstrap navigation by default. See here: How to restore the Bootstrap nav [walkthrough]
Sweet!!!. I thought I was going mad… Please close this ticket:)
