The map display is more useful when the names of the neighborhoods appear on the map. A mass of unlabeled POIs makes it hard to quickly see where a given neighborhood is. See https://wilmdx14.townwatch.us/neighborhood-map/.
Google has many features on Google Maps that they’ve chosen not to expose in the Maps API. Unfortunately marker titles is one of them. It is possible to do this by replacing Google’s markers with a custom overlay class (which would also speed up marker rendering), but I don’t have any ETA implement that yet.
