Just for the record - I have just updated Windy app on Android to latest version and it is now possible to change default layer. Wow, such a welcoming improvement. Thank you so much Windy team for this functionality. With Gratitude, Alex

I am too voting here for the ability to change default startup layer. App functionality has surprised above and beyond its name and original intention. I think it is time to stop being stubborn and move on with natural organic growth of it. Thanks, Alex
