Tabbed browsing...the cons

Tabbed browsing is here to stay for a while. IE has donned the new mask of tabbed browsing following the foots of mozilla and others. But all of them have the same problem as TOG points out in his design bug database. So whats the bug? The close tab and Close all tabs are close to each other and by accident you click on Close all tabs, grrrr....you lose all your tabs,..no Undo....user is at bay.... The fix? Move the close all from Close. Provide an Undo
