Hotbars+ (also known as "MultiHotbar" in earlier versions) is a mod for Minecraft that dramatically increases how many hotbars can be saved by paginating the vanilla hotbar storage system.
The mod works by hijacking the saved hotbar system Minecraft uses to use a different file to load and save from in place of the traditional hotbar.nbt, hot-swapping files for each page.
The requirements depend on the version of Minecraft you're using. To help guide you, here's a table:
| Version | Fabric Loader | Fabric API | Cotton Client Commands |
|---|---|---|---|
| 1.14.4 - 1.15.x | Yes | Yes | Optional* |
| 1.16.1 - 1.16.4 | Yes | Yes | Optional* |
| 1.16.5 | Yes | Yes | No |
| 1.17.x - 1.18.2 | Yes | Yes | No |
| 1.19 - 1.19.4 | Yes | Yes | No |
| 1.20 - 1.20.2 | Yes | Yes | No |
* = The mod will still launch without it, but you won't be able to run client-side commands like /hotbars+.
