Hi @Wayne-Coomer, thanks a lot for your feedback and suggestions, we're really happy that you like Windy! :-)

There is no "Home point" button such as the one in a car sat-nav, however, I think you can do with your "Favorites": the one you set up first will always remain on top of the list. Another thing is the "Find my location" button (right at the top of the Menu bar - both on desktop and in the app) - which takes you to "where you are on the map" at that moment. And you can choose your "Start-up location" in Settings (only on desktop) - which should then be synchronized with the homepage (the "house" icon) in the app.
