When a user receives tasks in Forms as part of a team and even just an individual, and they receive email notifications about those tasks, it's great because they can get notified immediately.
What I think happens a lot though, is that other members of the team might have already completed the tasks the email is associated with, but the other users have to click on the link to verify that it has already been completed.
It would be great if a Live Status could be included in email tasks to show what the current status of the task is without having to actually open the task in Forms. I would expect an image to be used as well as text.
