The shortcuts/hotkeys to ACU and Rangers are great, especially how it brings up the closest building when there are more than one in the park. The system as is works fine. However, on the largest parks with a major break out it’s a hassle to try to get all ACU units on mission. It’s not critical, but changing the hot key for ACU and Rangers to open a master list of all units instead of the nearest building (ACU Center or Ranger Station) would be a big help for crisis management.
