Love it! Rated 5 out of 5 stars

LOVE IT!!!!
It is great being able to write up an email and look at my references on the same page (google reader, google gadgets, custom). The add-on works well with the google lab extras I have applied and there was no conflict with my other add-ons (I am running 55 plus). I had some questions about the Integrated GMail and the author, Michael, was quick to respond. (unfortunately, google docs will not load as part of this new google mail page due to google design of the docs page.) This add-on is great now and has potential to continue expanding into an incredible add-on. This is a must have extension!!

This review is for a previous version of the add-on (2.0.1).
