As you zoom out the icons become more prominent to help with planning at the furthest zoom but relatively unobtrusive at the closest zoom.
This mod also includes re-worked canyons and escarpments.

PLEASE NOTE:
As of version 1.1 I've added in a thin border for the unit tokens which makes it much easier to see their stacking. Unfortunately, these files aren't handled through the graphics mod system of the 'GraphicAlt' directory so if you wish to use these they will need to overwrite the files in the games 'graphics' directory.
