Hi dwaradzyn!
thank you for your suggestions, i can understand your point of view and i'm trying to make a better work...
...you know, icons should be always at half way from beautiful graphics and easy understanding... so find the right compromise is not so easy.
Concerning the road symbol for the 3d map, it was my first try but i found that it seems a track.. so i'm still looking for it.

At the end of work, replace only the clear blue to adapt to different themes color is the easiest part. (there will be one blue, one red, one green and so on....)

Concerning the satellite bars, is it possible to modify the color when the fix happens?

PS.
the modified zoom function using the SHIFT key is very very useful. Really great! When used in offline mode maybe interesting if it was also possible to have a lock for this.
