When using “Defer until”, it would be nice if the drop-down for the “Due” date would start at the “Defer until” date rather than today.
Just now, for example, I set a reminder to cancel a recurring subscription (not OmniFocus 😎) whose next billing date is some months away. I set the “Defer until” to the date I want, which means clicking “Next month” in the drop-down several times and then doing the same thing with the “Due” drop-down. Since “Due” should always appear on or after “Defer until”, it would be nice if the drop-down started with the “Defer until” date.
This doesn’t mean that “Due” should be auto-set to the “Defer until”, though, because it’s still legitimate to defer a task but not have a due date. Only the action of clicking on the calendar icon should trigger the above behaviour.
