Neither option appears in the Configure Toolbars menu
option.
I hope I'm missing something obvious!
You can use either the Menu bar at the top:
Settings >> Toolbars -- turns the individual toolbars on and off
Settings >> Configure Toolbars -- lets you add remove things to the individual tool bars.
OR
Right click in an empty part of the toolbar and select Configure Toolbars from the menu.
Those options don't do anything. :) There are no options to not show either. In the Extensions menu are check boxes but they don't do anything either.
