Hi, if you have 2 locations with filled out hearts, they will eventually disappear from your search. You will access your favorite locations through Favorites section, or you can always set up your default location in Settings -> Start-up location and choose it from Favorites.
Anyway, you don't need to enter the exact address into the search bar in order to add the place to your favorites. You place the picker at the location and click on the heart symbol.
Nevertheless, you cannot search by street number on Windy.
