// ==UserScript==
// @name           Yahoo Mail New Ad Remover
// @namespace      nnat.yahooadremover
// @description    A yahoo mail new adver destroyer
// @include        *mail.yahoo.com*
// ==/UserScript==
// Author: Narayan Natarajan
// email: venkman 69 at yahoo dot com 
//       (you know what to do to get the email addy from above)
//========
// change log:
// Version 0.6
// Modified it to work with the new Yahoo mail
// Firefox extensions adblock and noscript can block the ad but this 
// script allows you to reclaim the lost sidebar space!
// Version 0.5
// modified it to work with new yahoo advert hidebar name change
// Version 0.4
// changed behaviour of ads to "hide" rather than move them.
// thought maybe that would be more efficient
// also took care of the new yahoo "hide" button (so cheesy of yahoo!)
// Version 0.3
// Added width modifier to message panes that are popped into another tab
// Version 0.2
// Changed the name to something a bit more recognizable
// Version 0.1
// Adbeta released
//========
// Bugs
// not perfect, sometimes yahoo does not reload the page and does 
// some optimization by redrawing stuff around
// it does not recognize this and will not modify the width of such
// message panes.
