I think that a note in http://extjs.com/deploy/dev/examples/tabs/tabs.html will be a great help.

Your suggestion will die here. You probably need to specify something in one of the doc threads:
http://extjs.com/forum/showthread.php?t=40317
http://extjs.com/forum/showthread.php?t=13818

or add to an appropriate FAQ in the wiki, which you can edit.
