I vibe coded a widget that remembers units that have been seen. It also removes them when they die or when a wreck is seen. It also removes any unseen units for more than 10 minutes (changeable timer in settings at hud panels/enemy intel)
It's basically a enemy unit tracker, also tracks statics but that can be disabled in the settings.
