I like that you added an email preview box, but it is inconvient to use. Even on my large screen monitor, when the preview box comes up, I have to scroll down to get to the View Inbox option, and then when I exit the email inbox, I have to scroll up to close the Preview Box. The View Inbox should be at the top right of the Email Preview box, and when selected should automatically close the Email Preview box. Seems like that would be more user friendly.
