I am currently working on Flatpak support for SFOS and would like to get it over the line for distribution. Then have to polish a bit XZ2/3 port as there are few issues with it. So, further development of Pure Maps will have to wait a bit, probably ~month.

However, there is a plan to rewrite navigation handling which should resolve some of the issues, possibly distance increase that you observed. Idea is in the head, just will have to write it down and test it.

As for zoomed out map - not sure. We do have rather small devices. Try to make a screenshot on Pure Maps, then one with zoomed out map, gimp it together and put on your car phone location. How much would you see in it?
