I get that, but I don’t think that an alarm is the same thing as due date. An alarm is reminder, which is usually set in a relation with a due date, but they don’t have to necessarily coincide or be used at the same time. For example, I might set a task with due date in a week, and set an alarm for 2 days before that to have time to complete it. Or just set a task due in a week without an alarm at all.
However, even assuming that we would use them as one as the same, I still didn’t find an option how to sort the tasks according to the alarm date or filter them using it. Am I missing something?
