Ah, ok. So this? Node Hunter for specific city
It would be very expensive for me to provide a button that displayed all of your un-finishsed streets in a city - both in the server/database as well as in your browser. Most devices would probably crash. That’s also why there’s an upper limit to the number of nodes that NodeHunter returns.
Let me know if that’s what you’re thinking, or if you had a different idea / different details.
