The mod has been redesigned to order.

Only remove creative items in tabs.

WAS IMPLEMENTED AS A TEMPORARY SOLUTION FOR UNIVERSAL BLOCKING !

{
  // -----------------------------------------------------------
  //              Item Obliterator by ElocinDev and Gvoper
  // -----------------------------------------------------------
  //  
  // How to add items?
  //   - They are json strings, so you need to separate each
  //     entry with a comma, except the last
  //   - If you start an entry with !, it will be treated as a regular expression
  //     Example: "!minecraft:.*_sword" to disable all swords
  //  
  // -----------------------------------------------------------
  // Do not touch this
  "configVersion": 2,
  // -----------------------------------------------------------
  // Items here will be removed from creative tabs
  //    Example: minecraft:diamond
  "blacklisted_items": [
    "!minecraft:.*"
  ]
}

"!minecraft:.*" - Disables everything that is in Minecraft. It also works with mods.

We can arrange to order a mod at Discord, my nickname is Gvoper
