Would like the ability to tag Users within the response sections of the ToDo, to ensure that the person is notified when a specific note pertains to them, or to ensure they know an action may be waiting on them. Creating a new ToDo may not be needed as multiple people need to work on the task, but only one may be needed to respond to one section of the ToDo.
Thank you for the idea. There are a couple different ways you can do this currently. One would be @ mentioning the user in a comment on the To-do. This will trigger an instant email notification to that user. Another option would be to add them to the To-do as an additional assignee. This will also trigger a notification as well as reminders when the due date is approaching or overdue.
