The buttons at the top of the email preview have been removed in Sortd 2.0, and rather added to the Gmail toolbar.

We are aware that there is no option there to add an email to your day plan.  You are still, however, able to add an item to your Day Plan when you have the mail open.  Look out for this icon at the top right.

We are considering adding the blue buttons at the top back, or adding a Day Plan icon to the Gmail toolbar, which would look like this.

If the Day Plan button is something that you were reliant on, we'd love your input on whether it's crucial to have the button in or above the mail, or whether using the icon is ok for now.  We are listening very carefully to customer feedback so don't be shy, please comment.
