I’m asking this question partly because I wonder if it is the intended behavior, or possibly a bug.
I use the Node Hunter feature, and of course love it. But I discovered behavior that I was not expecting. It seems that Node Hunter only shows uncompleted nodes if they are part of an uncompleted street. But if you have completed the street – remember that you only need 90% of nodes to complete the street – then Node Hunter will not show that node.
My personal preference would be that Node Hunter show all incomplete nodes, even if they are part of 90+% completed streets.
