To create a list that repeats its tasks every day follow these steps:
1) Create a Journal called Daily Routine
2) Set Daily in the frequency menu
3) Set "Automatically repeat tasks" in the Automation menu.
The tasks are copied/repeated when the day changes, this automation affects only the latest day's tasks (to manually copy tasks in a different day at once you can use the “Copy tasks…” buttons in the three dots menu). Tasks are not copied exactly at midnight, the automations are set to be completed within 3AM.
