WTH is there no dates in tasks lists?

Tasks lists should be extended by adding dates like deadline, periodic, etc…
With notifications.

Dates are already part of tasks. Times are not though, and recurring events would be a welcome addition.

Notifications you have to build yourself just like any other integration. If you have a specific notification in mind and don’t know how to do it ask in the Configuration topic area, someone is bound to help you out.
