@Suty I use a much higher resolution than the OP and I'm still bothered by the fact I can't close the Hurricane tracker panel. There should be an option to fold it away. If I put the window on either of my "portrait" monitors it takes up nearly a third of the window. Only when placed in my main "landscape" monitor does it take up roughly 1/6th of the window.

I still really like Windy, just wish I could fold away that panel when tracking a hurricane.
