The functionality would consist in being able to set up an alarm when specifying a time in a task. In this way, a task that is due or scheduled would ring the alarm in addition to the normal notification of the task.
This could work in a similar way as the classic alarm of the Iphone for example.
Thanks for the feature request. Is your idea to help you be more prominently notified of certain tasks? I wonder whether the ability to select a particular sound (which could be up to 30 seconds in length) when you set a scheduled/deadline/show on date would work for this? Not something currently planned but I imagine could be quite useful so you don't ignore certain tasks.
Thanks Matthew for your interest in this feature!
Yes, this would be to help noticing important tasks. Currently the notifications only consist in text notifications/banners on my lock screen, which are easily unnoticed or drowned in the flow of other apps' notifications.
The way I see it, the sound or vibration of the alarm should be persistent, as opposed to the current short sound/vibration that comes with the notification. It should be something that says "Hey I am here" until I effectively decide to switch it off (just like an alarm to wake up).
This would enormously help me notice certain tasks that I want to make at certain times.
A related option that I'd like is the ability to suppress the sound/vibration for some timestamped tasks, e.g. using a property or a tag. I have some items that I like to see on the agenda for the day but don't want to be notified about; but for others I do want to be notified.
