I'm working on the user interface. I've added a toolbar, icon, and some buttons (close, minimize, maximize). I have some problems: it does not always work.
I also set up the loading screen.
Holy Mother of Pearl that's AWESOME!
What about online map viewing and manipulation?
In the download section you can view and download online map.
The manipulation section is very basic. I'm doing this for a voluntary association: this program will always be used offline.
