A couple people I've seen use the app for the first time have missed the jump to current location circle on the map. Highlighting it or calling it out in the initial screen would help prevent that.

There was also a recommendation to display the current location dot on the map on initial load (not just after the current location is pressed). I'm partial to this, but also don't like apps that request location on load, so perhaps this would just be if location was already shared.
