Is it posible to import a KMZ file into Windy?
KMZ are zip archives containing KML files + other resources (pics, ...).
If you want to display the KML inside the zip, you would have to unzip it and then you can use omnivore.
You should be able to find plenty of resources by googling for "kmz leaflet", ie https://stackoverflow.com/questions/35867793/using-kmz-file-in-leaflet-map
@dburch try this:
right click, click Load kmz/kml.
Quick plugin, does not work for all kmzs and looses properties.
