The only probe is a mod that was born as an alternative to the Waila Mod. This mod is obsolete for the current version of the game, so if we want to continue having its functions, this mod can be a good alternative to the functions of Waila.
The mod is responsible for showing us information about any block or item in the game, or added by any mod. This information will show us two things, the name of the object and which mod it belongs to, and perhaps the most useful information about how this block works, which we would normally find in the interface of the block or the object in question. The operation is so simple that we only have to point the mouse to the object from which we want to obtain this information.
