I used Milestone for the first time this week. I made two existing tasks Milestones. I was looking forward to seeing milestone met when user completed the task. However, user relies on her calendar view to see what is due, and the Milestone shows only a symbol (?) and not the name of the milestone task on the calendar.
As a result, she missed her deadline.
What are the product expectations for the behavior of milestones when presented in the same places regular tasks appear?
