Nearby Jobs needs to be configurable with different ranges per region/country as the criteria for what goes as ‘Nearby’ varies greatly depending on the country. For the Netherlands 100 kilometers which is also the maxim range is probably more then enough. For the United States and Canada this is rather small and ranges much larger than 100km should be configurable. Therefore, this should be configurable by country/region as a default where it additionally can be adjusted as a per user setting in the users preferences.
What is the underlying problem do you intend to solve with this idea?
Ability to configure the settings per user/country and its size and needs.
How is the problem being addressed today, if at all?
