Use case: You have a list of tasks to work on. You want to work on them efficiently one after another.
What we have to do today (new tasks feature):
  1. Go to the task view and filter the list of tasks to work on
  2. From the top task, click the contact name. Do whatever you want to do on that contact (send email etc.)
  3. Hit the back arrow to go back to the task list
  4. Click the next contact
etc.
Proposed workflow instead:
  1. (same)
  2. (same)
  3. Instead of hitting the back arrow in the browser, you should be able to just hit the "right" arrow in the contact card (screenshot: https://drive.google.com/file/d/1O6ScQr6s1hn9zKjjOqgiJ_ryWm1Ihnbi/view?usp=drivesdk)
That way, you can just hit "next contact" and work on the task in that contact, until you've finished all your tasks.
ALTERNATIVE SOLUTION: It would also be just as good if there was a filter on Contact level, that allowed you to filter on contacts who have a task with a certain due date.
