Ability to change the accuracy of the enemy positions shown on the map/Abris/SA-page

It would be nice to have a setting in the mission editor which would change the accuracy of the information on displayed positions of known enemy units. So you might know that there is a Tunguska near the area, but the threat ring shown on the SA page would be off by 5 kilometers.

Also, when setting units as hidden, I see no reason for them to be also hidden in the mission editor screen. It complicates mission making.

Good suggestion, but you can achieve this by simply setting up the unit to move a little bit and redeploy, at the start of the mission.
