How do I make something a favourite? What does that mean?

On every home listing card, you'll find a little blue heart in the top-right corner. Click that to make a favourite, or click again to unfavourite the home. Once you've done that, you'll see that home appear with a blue pin on the map and you can search for your favourites using the main navigation bar, Homes/Favourites, or using the Filters screen.
