Found some bugs
The tide button does not work in the area of southern Italy including islands.
Radar refers only to the United States, part of the northern eruopa excluding totally Italy.
The map is not able to move from all points on the screen, but only from the left of the screen.
The tide amplitude is so small in the mediterranean sea that it is neglected for navigation. There is very little interest to add this feature in this region. So this not a bug !
The radar layer has not yet been implemented for Italy. It’s not a bug either !
I don’t know why you have problem to move the map on your screen, but someone can explain it, may be. That’s probably a bug.
