The iGoogle settings are fairly well hidden. On this page you can do helpful things like:

• Hide or Show the Google Chat widget
• Change from Two or Three column layouts
• Easily see/share/delete what gadget you have installed
• Backup and restore the page
• Export/Import settings to a XML file

I was interested in hiding the Gtalk widget on the iGoogle page because I don’t use it anymore. There are some helpful settings available that anyone who uses iGoogle should know about.
