OwO What's This
This modification is a port of the popular "The One Probe" mod by McJty, specially adapted for the Beta 1.7.3 version. The reworked version doesn't just transfer the functionality, but also adds improvements that are better suited for this particular game version.
How the Mod Works
When you point the cursor at any block or entity in the game, an information panel appears on the screen. The most important aspect is that this data is generated on the server side (or client side in single-player), which allows displaying information that would be unavailable through client-side analysis only.

Integration Capabilities
Other modifications can register their own information providers, which will be automatically added to the general data panel transmitted to the player. This system allows creating a universal information environment regardless of the number of installed mods.
