I feel you only too well... After having been hyperventilating A LOT a couple of days ago after having updated to v39, currently my mood is a mixture of mourning acceptance and continuing to provide constructive suggestions to the Windy team:
I'm afraid, we have to accept the new layer-list. But I really really hope, that well formulated, constructive suggestions might lead to some positive changes with regards to the new location selection process. I can only hope, that the Windy team will positively answer to my prayers in this respect...
