How do I make one particular scrap last longer?
Short answer: Open the scrap's lifetime/pin menu on its card or in the preview and pick a longer time, up to 6 months. Only that scrap changes; your default for new scraps stays the same.
Use the scrap's lifetime/pin menu — on the card itself, or in the preview — and choose a longer time. Options run from 5 minutes up to 6 months, and the card's countdown updates straight away.
This doesn't change your default for new scraps; it only affects that one card. If you also want it easy to find, pin it so it stays at the top.
