As the subject suggests - it would be helpful to see a report of when a task is completed compared to when it was due. When the reschedule feature isn’t being used it will help with activity tracking and monitoring to see just how long it’s taken to complete the task.

Other viable options
- adding formulas and date functions (like datediff) to reports, or to be able to define custom fields that are formula (also add the option to add custom fields to activities)
- adding a built-in field to activities that outputs the difference between due date and completion date.
