Creative Tabs Tweaker

Creative Tabs Tweaker reorganizes the creative inventory on Forge 1.12.2. Players can remove tabs added by other mods, move individual items from one tab to another, and create new custom tabs. Changing the contents of the items tab is also covered, so a modpack can group its items in a more orderly way.

Running Minecraft once with the mod installed generates a configuration file. Its entries follow a set of rules that describe which tabs to remove, which items to move and how custom tabs are defined. Custom tabs also need a language file and an image, both placed in the resourcepacks folder, so their names and icons can be shown in the creative menu.

Only the client needs the mod, because the creative menu exists on the player side. Files are released under the Creative Commons Attribution Share Alike 4.0 license, which is not an open source license, and the source code is publicly available. The author credits MCreator, Blur, OptiFine and SEUS.
