Neighbourhoods as subcategories of major cities
I'm using the app to bookmark places overseas. So when I bookmark something in New Orleans, for example, the neighbourhood 'French Quarter' comes up, instead of 'New Orleans'.
Ideally, whichever city GPS registers you as being in is separated into neighbourhoods, and the rest remain grouped into major cities.
Manually is fine.

When you bookmark a place in a city that is different from the one you are currently in, we show you a view of all the bookmarks in that city.
Click Back at the top of your screen. You will be brought to a view of all the bookmarks in your current city broken down by neighborhood. At the bottom of your list should be an Other Cities section that says New Orleans.
