Better Advanced Tooltips: The Ultimate Item Data Inspector
Every Minecraft player has stared at an enchanted book or a mysterious spawn egg and wondered what was really going on under the hood. For builders, modpack creators, and datapack authors, that curiosity is a daily necessity. Better Advanced Tooltips answers those questions instantly, turning the standard debug screen into a full-blown item forensic toolkit. Instead of guessing which tags an item carries or what components define its behavior, you simply hold a key and read the truth.
What Does Better Advanced Tooltips Actually Do?
At its core, this add-on expands the information shown in the F3+H advanced tooltip mode. Vanilla Minecraft already shows item IDs and durability, but this mod goes several layers deeper. It surfaces tag data, component patches, fuel values, and even custom chat icons, all without forcing you to dig through external databases or JSON files.
The mod is lightweight, client-side friendly in most setups, and designed to stay out of your way until you need it. Whether you are debugging a datapack or just satisfying your curiosity about a goat horn, the answers are one keypress away.
Supported Versions and Loaders
Better Advanced Tooltips is built primarily for modern Minecraft releases, with active support spanning the 1.19, 1.20, and 1.21 branches. It is developed as a Fabric mod, which makes it a natural fit for Fabric-based modpacks and lightweight client setups. Players running Quilt will generally find it works without issues, since Quilt maintains broad Fabric compatibility. If you are on a version older than 1.19, check the project page carefully, as component-related features only make sense on versions that use the modern component system introduced in 1.20.5 and refined afterward.
Key Features Explained
Tag Tooltips with the Shift Key
Holding Shift while hovering over an item reveals its tags. The mod is smart about which tags it displays based on the item type, and it uses distinct icons to signal the category:
- Sword icon: standard item tags
- Grass block icon: block tags for any placeable block item
- Pig icon: entity tags, useful for spawn eggs
- Bucket icon: fluid tags for buckets and fluid containers
- Painting icon: painting variant tags
- Enchantment icon: enchantment tags, perfect for enchanted books
- Piano icon: instrument tags for goat horns and similar items
- Banner icon: banner pattern tags
If several tag types share the same name, the mod merges them onto a single line, which keeps the tooltip readable instead of turning it into a wall of text. This is a small detail, but it makes a huge difference when you are inspecting dozens of blocks in a row.
Component Patches with the Alt Key
Holding Alt while hovering an item shows its component patch, meaning the components that differ from the item's default state. This is what used to be called "Custom NBT" before the component system arrived. It is invaluable when you want to know exactly what makes a renamed sword or a custom potion unique.
Full Component Maps with Alt + Shift
Press Alt and Shift together, and you get the complete component map for that item. Custom components are highlighted in yellow, so you can spot your own modifications at a glance. This is the fastest way to audit a shulker box full of tweaked gear.
Fuel Values and Chat Icons
Hold Shift over any fuel item to see its exact burn value, which is a lifesaver when designing efficient furnaces or auto-smelters. The mod also bundles a set of chat component icons, documented in its font and icons JSON file, which modpack authors can use to enrich their own interfaces.
For players who want the fastest possible setup, the foxygame.net launcher offers a one-click install path for Better Advanced Tooltips, pulling the correct build for your selected Minecraft version automatically so you never have to match loader versions by hand.
How to Install Better Advanced Tooltips for Minecraft
Getting started is straightforward. First, confirm you are running a supported Minecraft version and have Fabric Loader installed. Next, make sure Fabric API is present, since many Fabric mods depend on it. Then place the Better Advanced Tooltips jar file into your mods folder, which you can find inside your .minecraft directory. Launch the game through your Fabric profile, and once you are in a world, press F3+H to enable advanced tooltips. From there, hover over any item and hold Shift, Alt, or both to explore its hidden data.
If you plan to download Better Advanced Tooltips, always grab it from the official project page to avoid outdated or tampered builds. Keeping the mod updated matters too, because Minecraft's component system continues to evolve with each release, and older builds may not display newer component types correctly.
Who Should Use This Mod?
Better Advanced Tooltips is not just for hardcore developers. Datapack creators rely on it to verify tag assignments. Modpack authors use it to confirm that custom components applied correctly. Even survival players benefit when they want to check fuel efficiency or understand why a traded item behaves strangely. It replaces guesswork with certainty, and that is exactly what a good debugging tool should do.
Final Thoughts
Better Advanced Tooltips fills a gap that vanilla Minecraft has always left open. It transforms cryptic item data into readable, organized information, and it does so with a design that respects your screen space. Whether you are troubleshooting a complex modpack or simply curious about the tags behind your favorite block, this mod deserves a permanent spot in your loadout. Install it once, and you will wonder how you ever managed without it.
