I have seen this talked about before and think it’d be a highly requested/used feature, but I don’t see a trello card for it?
I think some sort of calendar/agenda view where you could see dated to-do’s on a visual calendar would be ace. Integrating with Google Cal is one way but if this feature were native to Dynalist then you could have more powerful features like dragging an item on the calendar to change its due date, or completing/editing an item right from the calendar view, etc.
