Hi Gary, another good tool from you. Thanks! Maybe you make also one for switzerland.
By the way, can you make smaller intervalls for AreaCheck and MotorwayCheck? I have always to wait one or two weeks (areacheck is from 31.8.) to see if the errors are fixed.
Greetings Marcel

Yes i also think there should be a link (hide big changes) to view only changes that are more local (smaller areas).
