XaeroHeadTracker

Beta, Forge 1.20.1. Requires Xaero's World Map. To see other players' heads, the mod must also be installed on the server.

• Players who left before you joined now appear on your map. The server remembers the last position of players who were sharing (dimension, time since they left, skin) for 7 days and sends it when you join. It is saved with the world, so a server restart keeps it.
• Privacy: when you share your position, your last position stays visible to the players you chose for 7 days after you leave, or until you come back. Turning the game rule xaeroheadtracker:allow_sharing off erases all stored positions.
• Players you never saw now show their real skin (or Steve/Alex) instead of a red square.
• After 60 minutes, the time since a player left is shown in hours.

Compatible with 2.2.x clients and servers (the new data is optional), but the server and the players need 2.3.0 to see players who left.
