The My location widget in Web App Builder is a nice addition and is working fairly well on all of our maps with secure data sources, however, it would be nice to integrate this widget with some of the other location-specific widgets. For example, if I have an app with the near-me widget enabled, it would be nice to be able to configure that widget to honor the location captured by the My location widget.
Another path might be to build the My Location functionality into those location-specific widgets. Near the search bar that is part of the Near Me widget for example, there could be a My Location button added as an alternate input besides address search or placing a point on the map.
As it stands the My Location widget does show my current location, but doesn't lead users into any of the other purposes of the map.
