Pros:
-Allows you to look at all of the emails, read and unread, in your inbox, as well as archiving, moving, deleting, etc.
-Easy navigation for looking at emails, exiting to inbox, and closing out of the app.

Cons:
-Requires you to select the emails before performing the actions listed above instead of having the action buttons available after hovering over the email
-Slow to load
-Limited to one inbox/account

Overall, this add-on has potential, but is not the best that it could be. Consider fixing the cons above, and this could really be a tremendously useful add-on.
