Jade/The One Probe/WTHIT plugin that shows what Block and Block Entity is inside Mekanism Cardboard Boxes. When installed alongside Mekanism, and one of the supported plugins it will add two new sections: "Block" and "Block Entity" to the Cardboard Box tooltip. If it contains a monster spawner it will also show what mob it spawns.
The tooltip will have information about what block and block entity is inside the cardboard box.

The default Cardboard Box tooltip has been changed to match the one provided in Mekanism 10.5.

The inspiration behind this mod was the lack of QoL information on Cardboard Boxes. I use them whenever Mekanism is installed to move monster spawners. But the annoying part is when cardboard boxes pile up the storage network without any information on what they contain.
