Separate Fabric builds for Minecraft 1.21.10, 1.21.11, 26.1, 26.1.1, 26.1.2, 26.2 and 26.3. Choose the JAR matching your exact game version.

• The ghost block of 1.11 is gone. When a click waited one tick for its key and you were still holding the button, Minecraft placed at once with the old item: one extra use nobody pressed. With real 80 ms clicks that happened in 25 of 25 bursts in 1.11.0; in 1.12.0, and in Vanilla, in none.
• The preview comes back. One disagreement between the preview and the game used to switch the preview off until you changed world, and the hotbar felt slow for the rest of the match. It now returns after three seconds.
• A held key no longer steals the slot. Holding a hotbar key on the keyboard and tapping a slot bound to a mouse button sent you back to the held key. Only real presses count now.
• Nine new switches, in a new settings screen with tabs on the left and the explanation of each switch on the right:
  • Guards: Hold guard, Ignore key repeat, Mouse-like keys (off).
  • Feel: Offhand swap preview, Slot pop, Preview recovery, Combat items too. Hotbar preview, No equip dip and Smooth attack indicator can now be switched off too.
  • Monitor: a response meter that shows, in milliseconds, how long your last hotbar key took to reach the screen and the game tick; and a tick shape monitor that counts in your own packets the things a server can tell from Vanilla.
• Nothing aims, chooses a slot or acts for you, and nothing is sent sooner than Vanilla would send it. Tested against Grim Anticheat with its experimental checks on: no alerts.

Your saved order and switches are kept when you update. The new ones start on, the fastest the screen can answer, except where it says off.

Requires Fabric Loader 0.19.3+. Minecraft 1.21.x uses Java 21; Minecraft 26.x uses Java 25. Install Fabric API for localized mod text and Mod Menu to reach the settings button. Client-side only.
