About this Mod

A fork of the Release 1.12.2 version of The One Probe by McJty for Beta 1.7.3 along with some improvements and providers more applicable to the version.

OwO What's This provides an ingame overlay about the block or entity that the user is currently pointing at, this overlay driven by the server (or the client in case of singleplayer) which means it can display information inaccessible only from the client. Other mods can register their own providers which will be seamlessly added to the probe information sent to the player's screen.
