Remove the Chat box from the left pane on gmail
Can I completely prevent the download and usage of 'Chat' in Gmail?
When you turn off the chat in Gmail by clicking the given link, you are logged of the chat. But the files/scripts required for running the chat are downloaded anyways. Like Buzz, you can completely turn it off. What I want is Gmail Labs like functionality, where you can completely turnoff the extension and it won't get downloaded again.
