Allow to show weather at a point with arbitrary coordinates

[Korb]

That is, to interpolate the weather forecast between the nearest forecasts to the specified point. The point can be specified by the user on the map, or received as the current location. This is especially true when there are no settlements offered by the application near the place of interest.

This is also convenient when there is no GPS but Internet connection is still present (indoors, etc.). Sometimes Network Location doesn't work.

Also it's useful for regular travellers.

Something like a list of bookmarked locations and a search bar would be enough.
