Would you consider adding (as a Premium feature) a graphical interface to compare forecasts from different models for a single parameter at a time? The user could choose e.g., wind speed, or temperature, or precipitation etc. and see graphically how the set of different forecasts evolve over time. I think it would be more user friendly than the current compare forecasts function.

I attach a screenshot from Windy.app (which I believe has lower quality data, but a better user interface from which you can draw some inspiration for future improvements, in my opinion).
