Has anyone tried a UI mod to highlight enemies? There must be something in the code for it as they are highlighted behind terrain, but for the life of me can't find it, even when digging through the various UI files in the main game

Just after a mod that leaves the red highlight on all enemies constantly. Have been using a lot of minion/pet builds recently, but constantly run into the issue of having too many things on the screen and being unable to distinguish between friend and foe; and when you get later into the game, knowing when an enemy is anywhere near you becomes vital to survival...
