Sneaky NameTags

Makes player nametags only visible when:

Directly targeting them
Player isn't crouching
Client side
This mod is ideal for roleplay, as names will not be visible unless you are close and looking directly at the person. This way:

It is more immersive.
You don't sacrifice the ability to see names.
If someone doesn’t want to reveal their name, they can crouch— even if you're close and looking at them, you won’t see their name.
