Where's My Base? adds the command /wmb that will tell you the coordinates of your base.
WMB automatically tracks where your base is, and updates when it changes. When you interact with a bed or a respawn anchor, WMB will remember where you are. Your base is stored independently for the Overworld and the Nether.
Supports English, German, Russian, Japanese, and Brazilian Portuguese.
Type "/wmb" to see where your base is.
Type "/wmb commands" for a list of commands.
WMB's default hotkey is B. You may change this in your Minecraft settings.
