Player Name History Lookup (for Fabric)

An extremely simple and lightweight fabric mod which provides easy access for looking at player name histories.

Use /names <Player Name> (or /n <Player Name>) - look up the username history of the name supplied.
Use /namemc <Player Name> (or /nm <Player Name>) - search the name on NameMC.

Made for 1.16-1.18.2, however, can be self compiled for other versions (if they work)

Drag and drop the downloaded mod file into your mods folder - the same as any other mod.
