It's not clear for me when the touch screen won't do anything, why there's no touch gesture for zooming and what a simple tap on the display showing a map does.
When I zoom out to display middle europe and tap on the screen once, the map shows Greenland or so, depending if I've touched the center of the screen or the upper or lower screen area. I didn't find a strategy where to tap to move the map into a specific direction - anyone who can give me a hint?
