Rated 5 out of 5 stars
E-mail and calendars are perhaps the most important internet services at both work and home. And this extension helps you keep up with both, all in one page. No need to keep 2, 3 tabs open, just to keep up with appointments, messages, etc.
And what's even better, the developer understands how important the extension is to the users. He is easily reachable, and attends to bug fixes with utmost timeliness.
