@Fellfrosch: thanks! I think the first version was better in terms of an item in the icon signifying navigation (rather "active" part of the software) against geocoding (searching loop). Maybe it has to be bigger, but that I don't know.

I tried to reduce the icon to the sizes corresponding to the app grid. I don't think you could see the color gradients on Africa with such size. If you compare your icon with the browser icon on SFOS, you could see that the browser has simplified color scheme which is actually OK for an icon.

Many SFOS icons have the main image surrounded with some border. This goes for browser, messages, settings. I guess, we could introduce the similar border for the icon as well.

If we want to put into the center the navigation symbol, then its good to ask whether we keep WhoGo and Poor Maps icons? If we do, I suggest to tune them later as well to introduce better visibility. If you look closer on night mode screenshot that I posted, it has location icon with small border around it which helps to see the location on the map (compare with the day mode). But, as such, I would like to keep the icons for location (still and direction) after such minor adjustment.

Please note I am far from any arts designer and my understanding of used colormaps is limited. I don't know whether we have to make it with larger contrast or not.
