I like clicking on the map to make my route / determine distance.
I’d only use this feature to find the closest untouched node / street. Whether this is done as a single button “find closest unrun node / street from your start point”, or as a map “show closest N nodes”, or “show all unrun nodes/streets within X km/miles”, it all achieves the same goal and support it. Similar to my comments here:
Custom distance areas (not exactly a city).
I “finished” running my city, and unlikely to run the surrounding towns. I’m still looking for little motivational goals which could include running to the nearest untouched nodes slowly spiraling outward (thanks finally for Hard Mode!), or alternatively running all the city streets X number of times if that could be tracked…
