What an excellent feature, and cements the fact that Windy is thinking outside the box and pushing to progress the fine art of weather exposition..
- The time and therefore weather should be presented along the route correct for the predicted time of arrival.
- Maybe actual route planning for road traffic - maybe as extra chargeable, tie-in with TomTom or another route provider?
- use a small icon of the intended user, car for car journey, plane for flight etc.
Those are my thoughts so far, but a great feature, look forward to it arriving on mobile.
