Hi there,
a nice addition to the dates on the bottom of a card would be a start date, end date and a date range option. This could ensure the card appears either on the start and end dates or daily if a date range is set. Maybe this could be extended to a repeating date as well.
It would be useful as I use this to plan my projects and having the card appear automatically would be amazing.
Hope that makes sense. This would be useful as well for tasks management.
Great app
