Best Gmail manager & notifier addon Rated 5 out of 5 stars

I like Gmail manager more than every other mail checker I've tested, coz' it's the one that shows the more about received mails (various accounts) in the less intrusive manner.

Am testing Shiretoko (FF 3.5) and already missing Gmail manager. Hope I won't have to keep using Gmail Notifier which much much less useful!

This review is for a previous version of the add-on (0.5.7.1).
