Recurring tasks
The standup, the invoice, the Monday review. Give a task a rhythm and you never recreate it again. Only the next one ever sits on your list, already carrying its owner, its priority, and its estimate, so the list stays honest instead of clogged with copies.
Recurring tasks, set once from daily to yearly. Only the next one shows on your list, with its owner, priority and estimate. Skip a week or stop anytime.
