Bag Tabs

Bag Tabs is a NeoForge mod for Minecraft 1.21.1 that adds a tab strip to inventory screens for bags and other portable storage items you are carrying.

The goal is simple: if you are carrying a bag, you should be able to open it directly from your inventory without moving it into your hand first.

What It Does

• Adds a tab bar to supported inventory screens.
• Shows one tab for each carried bag or portable storage item the mod recognizes.
• Lets you click a tab to open that bag directly.
• Keeps the tab bar visible while you move between supported bag screens.
• Highlights the currently open bag.
• Supports drag-and-drop insertion onto supported bag tabs when the bag can accept the carried stack.

Included Content

• A built-in Bag Tabs bag item.
• 27 inventory slots, like a single chest.
• Dyeable bag colors.
• Crafting recipe.
• Creative tab with the base bag, all dyed variants, and the Bag Namer tool.
• JEI entries for the dyed bag variants.

Tab Features

• Bag tabs use the bag item icon for normal mode.
• Compact mode replaces the icon with the bag name.
• Dyed bags tint their tab background.
• Pinned tabs always appear first.
• Pinned tabs can be reordered by drag-and-drop.
• Tabs can be locked to disable pinning and reordering.
• Overflow arrows appear automatically when more tabs exist than can be shown.
• Mouse wheel scrolling works over the dock.
• Fullness indicators can be shown on tabs and toggled in dock settings.

Dock Features

• Dock to the GUI bottom, top, left, or right.
• Dock to the screen bottom, top, left, or right.
• Floating horizontal and floating vertical modes.
• Per-player, per-world saved settings.
• Global default settings plus per-screen overrides.
• Remembered scroll position per screen.
• Adjustable X/Y offset.
• Adjustable max visible tabs.
• Optional compact layout.
• Optional fullness indicator.
• Draggable in-game dock settings popup with live preview.

Bag Opening Behavior

Bag Tabs supports two kinds of bag opening:

• Direct support for bags with native or compatibility-backed integration.
• A fallback hotbar method for unsupported portable storage items that still look like bags or containers.

When a bag is not fully supported, the tooltip says:

• Mod not supported: uses hotbar method to open

If no warning is shown, the bag is using native or compatibility-backed support.

Current Compatibility

Bag Tabs currently includes compatibility support for:

• Bag Tabs bags
• Traveler's Backpack
• Sophisticated Backpacks
• Dank Storage

Other portable storage items may still appear as tabs and may still open through the fallback hotbar method.

Bag Namer

Bag Tabs includes a Bag Namer tool that can rename portable storage items.

• Works on supported bags and inventory-like items.
• Uses an in-world style GUI with input and output slots.
• Does not close after each rename, so items can be renamed in batches.
• Drops its contents if you leave the screen.

Controls

• Left-click tab: open bag
• Right-click tab: pin or unpin
• Drag pinned tab: reorder pinned tabs
• Mouse wheel over dock: scroll visible tabs
• \ by default: open last bag

Notes

• Bag Tabs is designed to stay attached to existing inventory screens rather than replacing them.
• Unsupported bags may behave differently depending on how their mod handles right-click opening.
• Some mods may still need dedicated compatibility if they do not expose normal item-use behavior.
