Entity Status In-World Health Bars

As well as the corner panel, Entity Status can float a small health bar above entities directly in the world, so you can see at a glance which nearby mobs are hurt without having to aim at each one.

By default these in-world bars use the Damaged and Nearby activation rule - they appear over entities that are within range and are not at full health. You can change this to always show nearby entities, only show what you are looking at, and several other combinations, so the bars stay as quiet or as informative as you like.
