Friendly & Enemy Nametags

Only Version Currently is 1.21.8 FABRIC

This client-side mod allows you to mark players on servers as either friendly or enemies. Its great for PvP in large fights because it lets you quickly identify allies or enemies.

It will put a green or red box above their username that indicates their status. This only shows up when their nametag is visible and in render distance, and not when they are invisible or behind walls. Because of this, the mod is generally safe to use on most servers, but you should always check with a staff member! People you tag are saved between sessions.
