Colored Satellite Icons

Looking4Cache have a function to save power by reducing the GPS accuracy based on the distance to your current target. With the default settings your position will be less accurate if you are more than 100 meters away from your target. With the satellite button on top of the map you can override this automatism.

Yellow satellite: Low accuracy, because no target is set or more than 100 meters away.
Green satellite: High accuracy, because you are closer than 100 meters.
Yellow satellite with a lock icon: Low accuracy, because you overwrote the automatism.
Green satellite with a lock icon: High accuracy, because you overwrote the automatism.
Stoked through: GPS turned off.

The settings (distance to the target and accuracy) can be changed in the configuration.
