Save: tap the heart (♥) on any card — destinations, day plans, hero inspirations. You'll find them on the Saved tab.
Collections (folders): Saved → "+ Create collection" → name it (e.g. "Roadtrip 2027"). Then add individual cards to the collection via the "+" button next to the heart.
One card can be in many collections — the same Bali can be in "Diving trips" AND "Family trips" folders.
Quick add inside a collection — Open the collection → "Add cards" → see all your saves that aren't in it yet. One tap = added.
Guest mode: collections work without sign-in — they save to localStorage. On sign-in they migrate to your account and sync across devices.
