If you have always wanted to see Google Reader and Google Calendar inside your Gmail account then you have just got your prayers fulfilled. You don’t need to open any new window to see the Google reader and calender. A set of Greasemonkey now allows you to add both Google Reader and Calendar below your emails.
The Google Calender Seamless Integration script loads the Google calendar seamlessly into the gmail interface below the inbox using a gmail native navbox. The Google Reader Seamless Integration is the script which loads the Google reader just like the previous one. You should have Greasemonkey extension installed in your Firefox in order to do that obviously.
These scripts also saves you some system performance as you don’t need to open three different tabs. These user scripts are only compatible with your proper Gmail account and they wont work on your Google Apps account.
