Bob's Hotbar Optimizer
Optimizes delay between switching hotbar slots.
About this Mod
Bob's Hotbar Optimizer removes the delay between switching hotbar slots that Minecraft has. This is done by making Minecraft process switching slots as soon as it receives the input. Normally, it waits until the next tick. Minecraft's slot processing works in a numerical order, from 1 - 9. If you're on slot 9, and want to switch to slot 6, you must wait for it to be processed in the next tick. This can be annoying in PvP as well as other situations.

Does Bob's Hotbar Optimizer need to be installed on the Minecraft server?
No. Modrinth marks Bob's Hotbar Optimizer as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does Bob's Hotbar Optimizer require?
Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.10, 1.21.9. Files for different loaders are not interchangeable.
Bob's Hotbar Optimizer is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
