Is it possible to change the designs of the widgets created through the widget constructor?
If the above is possible, do we need to receive a special permission / license to do so?
For example, we would like to change the widgets' colors to match our site's color tone & manner.
Another example, we would like to use our own original icons instead of the icons provided in openweathermap, because we would prefer a simpler display for our users.
It is not possible. The widgets are provided as the are.
We might to add some other design in the future.
