## Adds a copy of the bookmark bar into the toolbar to the right of the locationbar
#
# 'Other Bookmarks' and the Reading List are not shown.
# You'll probably want to hide the existing bookmark bar through the right-click menu
# as well as launch with --bookmark-bar-ntp=never
# The location can be changed by moving the position in chrome/browser/ui/views/toolbar/toolbar_view.cc
