Create addon: Info Display

The addon lets a player place an information panel on a surface and read the contents of the storage block that sits on its opposite side. Two panel types exist: one reads an Item Vault and one reads a Fluid Tank. A panel can be placed on any of the four horizontal walls, on a floor where its face shows upward, or on a ceiling where its face shows downward. Panels can also be placed underwater, because they are waterloggable.

The addon requires Create and runs on client and server, so the server and every player need it. Files are published for NeoForge 1.21.1, and the code is open source under the MIT License, which allows free use in modpacks. Two catalog mods, Create: Bigger Vaults and Create more fluid tanks and pipes, use the same storage blocks this addon reads.
