The most active users of MapSphere have got very large tracks from different travels and it was slow and hard to view all of them. In the new version of MapSphere the tracks can be displayed day by day or in any time interval, they indicate their direction and use more colors. Finally, you can see the tracks in the 3D mode.
Other changes are intended to make the using of MapSphere easier.
