(to clarify, I'm not saying that *no* gnome apps have borderless tabs -- gnome-terminal & the epiphany web-browser are two examples that lack a border below the tab. On the other hand, nautilus & gedit & the midori web-browser all have a border -- admittedly because of a small border around the whole content area, it seems, as Dao points out in Comment 9. That's all the tabbed gnome apps I can think of right now. :))
