Create Tasks in Planner from an Email
Similar to an email enable SharePoint list, a feature that gives the Plan an email address. If one receives a to-do via email, they could forward the email to the Plan's email address and it'll create a Task in the plan, with the Subject as the title, and the Body as the description.
It would be nice to be able to create a task in planner from an email in Outlook exactly like you can with an "old style" task.

An integration through either email, REST API or any other way to update Planner, just like how it is with Pivotal Tracker or Trello.
