Places radar icons on the map to indicate the ideal locations to build radars for full coverage.
Also optionally tracks any radars built in non-suggested locations, by placing radar icons on the map at those radars' locations. This is intended to help if you want to come back later and clean up any unaligned radars.
Use the mod settings to change the desired positioning, or to disable the announcements in the chat window.
If you change the configured positioning in an in-progress game, all the radar icons will be redrawn to match the new settings.
