Fixed

• /inventorywizard on its own now sorts your inventory like /iwiz; before, only /inventorywizard <subcommand> worked.
• Default sort: redstone parts (repeaters, comparators, pistons, hoppers, levers, buttons, doors, rails) and decorations (carpets, banners, candles, lanterns, flowers, heads) now get their own categories instead of being lumped in with other blocks. In the client mod, crops you can eat (carrots, potatoes, berries) now sort with food.
• Paper: waxed copper blocks are no longer sorted as tools.
• A settings file that can't be read (for example after a typo while editing it by hand) is now kept as inventorywizard.json.bak before the defaults replace it, so your settings aren't lost.

Downloads

Pick the jar for your Minecraft version and loader. From 26.1 one jar covers Fabric, Quilt, NeoForge and Forge; before that, NeoForge and Forge share a jar and Fabric/Quilt has its own. Fabric and Quilt also need Fabric API. The Paper jar runs on Paper and Spigot 1.21 and newer: InventoryWizard-paper-2.3.4.jar.
