Some work is real but not for now: a reply that waits on Thursday’s meeting, a review that cannot start until next week. Leaving it on the board keeps it in your way, and changing its End date to hide it would make the board lie. Defer puts the task down until a time you choose, and it comes back by itself.

A deferred task is dimmed on the board and drops off your Now queue until its time arrives. When the time comes it returns, which Plankwork calls Bubble Up. A deferral changes what you are shown, never how urgent the work is.
