All of those features are paid features. You can learn more about them here Supporter Features - CityStrides
There’s not really an “unfinished roads” map view (yet?), but you can kind of get that view by visiting a city’s page from your profile (those links are special in that it shows you your complete/incomplete streets for the city). From there, you can show/hide individual streets and you can use Node Hunter (a paid feature) to show unfinished nodes limited to the current city.
Another thing that helps out a ton is that supporters see their LifeMap shown on the city page - this makes it even easier to spot areas you haven’t completed yet. The Updates on January 10, 2022 (Release 463) inadvertently removed that feature from non-supporters. I’m working on some LifeMap features that should include bringing that feature back to being free, but I don’t have a timeline on when I’ll be done with all that work.
