[Feature Request] automatically delete tasks when done (shopping list)

[zunami]

Hello!

my wish would be to delete tasks after they are done. i take the example of shopping list. after you have done these fast moving mini tasks, the completed tasks pile up in the background. these around again cause performance problems because they have to be loaded again and again.

My idea is an optional setting for the lists. Completed tasks should be deleted automatically after 30 days.
