NtwineSnooze
Park a card until later, and optionally tell it what to do when it wakes.
Snoozing a card takes it out of the queue until a time you pick. Click the alarm clock in its header, or press s, and it moves to the Snoozed band until then.
You can pick an hour, tomorrow morning, a few days, a week, or your own date and time. "Tomorrow" rolls over at 5am, so a snooze you set after midnight still means the next morning.
With a follow-up
If you attach a prompt to the snooze, the thread wakes up already working on it ("check whether CI went green and fix it if not") instead of waking up just to wait for you.
Until its sub-agents return
If a card's worker is waiting on its own sub-agents, you can snooze it until all of them are back. It returns to the queue only once there's something to read.
You don't need a snooze to wait on something outside, like a pull request, an issue or a timer. The worker watches it, and the thread stays out of the queue on its own.
