While the extension works for the most part, it's very slow if using a custom URL. In addition if you choose to disable the extension for troubleshooting or whatever, when you re-enable the extension it will not appear under options anymore and you can't modify the settings. I hope I can remove it and reinstall.

Be sure to remove the permissions you granted it after configuration using your current home page or changing to custom URL.

It's a good idea and just needs a little more tweaking before ready for prime time.
