Why does the email not allow "right click to open in new window"?
This new interface requires me to open ONE email, read it -- and then click the mail envelope, sign back in and open the Inbo to read another.
This is totally ridiculous.
How are you accessing the email? With just a browser and the webmail interface, or a desktop email client like Outlook or Thunderbird, or on a mobile device or what?
In List view, if you want to go back to the Inbox after reading an email, you can either click on the Inbox, or Back under the email toolbar (not your browser's Back button).
In Vertical or Horizontal view, click on the word Mail.
