Great app, use it almost daily. However, I have the same issue with Favorites. And I'd like to add a couple more suggestions:
A way to easily add/edit/remove/organize Favorites
The white star and white letterings showing favorites are not very visible once you start to zoom in on the map, to the street level. The white background, at least for my locations, make the white stars impossible to see. Perhaps using a colored, translucent box or some way to allow the favorite spots to show up against the background.
If searching by coordinates, and zooming in to street level, the coordinate "pin" disappears from the map.
Keep up the great work!
