The little heart lets you keep the murals you love.
Tap the heart on any mural to love it. Each one you love is saved to your own list. It's always a tap away from the heart in the top menu, so you can find your favorites again anytime. The more people love a mural, the higher it climbs in the overall rankings, a gentle sign of what the community enjoys.
Your list lives in this browser only, so if you switch devices or clear your history it starts fresh.
