I'm sorry, but normally I'm using Windy for weather forecasts for the location I am at or the satellite or radar layer.
So your suggested way wouldn't improve my user experience... either I have to change the model to have a more specific forecast (Icon-D2 for Germany) or to switch back to a layer except to two ones I always use before leaving the app.
Perhaps it's possible to implement an option to save the model the forecast which is shown after tapping the home button.
Thanks a lot for your help and the discussion :-)
