Rated 5 out of 5 stars

I really like this add-on! It's very convenient to have everything all-in-one instead of having to flip back and forth between different clients. I do have two problems:
- the 'tasks' never seem to work. I add a task, click 'save & close', and it never shows up.
- there should be an option to place the mode toolbar's 'mail' and 'calendar' icons onto the mail toolbar? Having two panels open minimizes real estate and can make it hard to view emails with large images. If those icons could be relocated, it would give users much more freedom to close/open panels without compromising functionality and ease of use.

This review is for a previous version of the add-on (0.8).
