Librarian

Librarian is a mod for Fabric that improves the saved hotbar system by adding new features and increasing the overall capacity with a page system. It is the successor to Hotbars+, a mod by the same author.

Features

Infinite saved hotbar capacity

Never run out of space in your hotbars again. Librarian introduces a page system which allows you to store as many items as you could possibly ever want or need.

Since this system is vanilla-compatible, you won't need to worry about having to convert or do any transfers should you decide to not use the mod anymore.

Better saved hotbar performance

Got a lot of data in your saved hotbars? Not a problem. Librarian optimizes the way the game loads and saved hotbars to run entirely in the background, completely eliminating some notorious lagspikes many have experienced while working with saved hotbars in the process.

Accidental overwrite protection

A common problem people experience with the saved hotbar system is the potential to unintentionally overwrite existing hotbars by pressing the wrong key, losing many items by complete accident in the process. Librarian tries to help prevent this from happening by comparing the data of the items being saved to that of the items already saved. If it doesn't exactly match, a prompt will come up asking for confirmation before continuing, potentially saving you and your items.

Renamable saved hotbars

To help facilitate distribution and organization, Librarian introduces a new vanilla-compatible hotbar metadata system which allows you to rename your saved hotbars to literally anything you want along with other bits of metadata like a description and even a list of authors. Names and descriptions support both chat color codes and also MiniMessage.

All metadata can be customized in-game with the client-side command /librarian meta*, but users can also rename their hotbar page by simply clicking the text in the creative inventory menu.

* - Some versions (such as pre-1.14.4) do not currently have client-side command libraries available, so with these versions you will have to apply the changes manually with an NBT editor. I personally recommend using NBTExplorer for this purpose.

Multi-version support

To account for those holding out on specifics game versions, Librarian supports a wide range of Minecraft versions as recent as 26.1.1 and as old as 1.12.2 (with the help of Legacy Fabric and Ornithe). I am committed to supporting as many versions as reasonably possible. The foundation of Librarian, while similar to its predecessor, is written with the goal of not relying on any particular version-specific code. This helps make it more future-proof in the long run.

Currently supported versions:

• 1.12.2 (Legacy Fabric or Ornithe)
• 1.13.2 (Legacy Fabric or Ornithe)
• 1.14.4 (Regular Fabric or Ornithe)
• 1.15.2
• 1.16.5
• 1.17.1
• 1.18.2
• 1.19
• 1.19.2
• 1.19.4
• 1.20.1
• 1.20.2
• 1.20.4
• 1.20.6
• 1.21.1
• 1.21.3
• 1.21.4
• 1.21.5
• 1.21.8
• 1.21.10
• 1.21.11
• 26.1.x
