We've made many changes on both the backend and the frontend of the app:• All layers are now free of charge• You can change the map style to one of several options. Access from the Settings tab• The Legend can also filter out certain markers you don't want to see• New pins for most data layers• Some high-volume markers are only visible at certain zoom levels. Turning on historical markers, for instance, may not display them immediately because there are too many. You need to zoom in to see them• The refresh button has been moved from the Layers menu to a button right on the map, in the upper left corner• Cleaned up the UI on the Search tab• Different types of alerts now have their own pin
