Address Map Widget - change default location

The address input widget currently defaults to TagoIO headquarters in Raleigh. We know where you are :slight_smile:

For users in other countries, it would be nice to be able to change this default location on the map to be more relevant to their customer base.

I am therefore proposing an addition field in the widget to set the default map location when where is no stored address in the widget (or a system wide default if easier).
