我是用gm的userjs
那个js是google reader和gmail整合在一起 //////////////////////////////////////////////////
// Gmail and Google Reader Integrator v2.0
//////////////////////////////////////////////////
//Author:
// Winston Teo, inspired by Mihai@http://persistent.info/archives/2006/10/13/google-reader-redux
//Description:
// This script integrates Google Reader into Gmail, built for Greasemonkey.
//Requirements:
// Firefox Browser
// Greasmonkey Extension
//Features:
// 1. Spilt-window view of Gmail and Reader on a single page
// 2. Links to collapse|expand either Gmail or Reader
// 3. Integrated Reader uses start-page as specified in Reader's "Settings"
// 4. Labels selector
// 5. Key 'v' to open Reader links in a new Window
// 6. Automatic resize of Gmail and Reader views
//Credits:
// Mihai @ http://persistent.info/ for having such a good code basis for me to learn and start with.
// I used some of his functions as listed:
// function newNode, getNode, hasClass, addClass, removeClass, getClassMap, updateFeedsCount
//Changelog:
// 1. 06-11-2006: Removed Reader on clicking "Contacts" link
// 2. 09-11-2006: Resolved variable naming bug; from READER_SHARED_URL to READER_BROADCAST_URL
// 3. 10-11-2006: Resolved default start-page issue; able to display "Home" as default start-page
