Junk Yard · Auto-clear, pins and deleting
What does pinning a scrap do in the Junk Yard?
Short answer: Pinning keeps a scrap at the top of the board with a pin badge, under the Pinned filter, and protects it from the curtain's two-finger-tap delete. It still clears on its normal timer.
Pinning keeps a scrap at the top of the board so it's easy to find again. Pinned scraps wear a small pin badge, appear under the Pinned filter, and can't be deleted by the curtain's two-finger tap.
Pin or unpin from the card's lifetime/pin menu or from the preview. Unpin drops the scrap back into the normal order. Pinning is about order, not lifetime — the scrap still clears on its timer. See Does pinning stop a scrap from clearing?
