I love windy, not only from a visual perspective, but also for the data it provides. Everyone I've shown it to is really amazed by it, and it's far easier to use than most weather sites. Keep up the good work!
I would really appreciate the ability to set an alarm/notification for wind gusts exceeding a certain speed. In my area, the difference between wind speed and the gust speed can be 50km/h or more, and strong wind gusts can (and have) destroyed plants on my balcony or sent furniture flying.
I saw another suggestion for the same feature, but unfortunately your search functionality here doesn't work for me on either Firefox or Chrome. Clicking a result just closes the list and doesn't do anything.
