CompassPlus

This simple server-side mod significantly expands the functionality of the regular compass in Minecraft. Now, by holding the compass in your left or right hand, you can see your current coordinates and viewing direction right above the hotbar.

The mod also includes a useful option to hide coordinate information from the standard debug menu (F3), which is especially convenient when creating modpacks. By default, the mod is disabled, so don't forget to configure the settings file before using it.
