Neat Plates is a nameplate addon that works with WoW Classic.
Use the command, ‘/NeatPlates’ or ‘/np’ as a shortcut to the interface panel for Neat Plates. On that panel, you’ll be able to select from a list of available themes. The theme you choose will affect both appearance and features.
Use the command, ‘/hub’ to configure the mechanics of those included themes. If you’re using a custom theme, it might have a different config tool.
