The main map should react to zoom and increase/decrease the part of the world map that it displays (with the transformation anchor as the current mouse pointer/the center of the map) within some reasonable values. The zoom should either react on the scrool wheel of the mouse or a setting in the preferences (maybe in percent of the natural size).
