So by default in Minecraft, only ops can place/use command blocks. However, on my server, command blocks have a double use: they are also used as a decoration item, as seen below. In this example, the command block (right side, below the redstone torch) opens the Vault door and is also designed to look like a Terminal. Thus the question being: Is it possible for a plugin to be made that can allow players to place these blocks? Of course, for security reasons, the plugin would have to also block players from placing NBT-altered comm blocks with potentially dangerous commands loaded already. If this isn't possible with a plugin because it's hard-wired into the MC server code, I can really just add another block textured like a Terminal, but I'm curious if this would be a possible concept. Edit note: This would not be a plugin to use command blocks; just to place them, as long as no modified NBT data is detected.
