I think adding a third category into some of the views on CityStrides would be a welcome one, and based on what I’ve seen and read about how the site is set up, I think fairly easy to implement.
When looking at a particular city, you can already view Incomplete and Complete streets. I think it would be great to have a third category that shows you just the streets that are very close, say ones that you’ve hit 90% of the nodes.
Hopefully this idea hasn’t been suggested already…
