WhatIsInThatShelf (WIITS)

Never wonder what's sitting on that shelf again.

WhatIsInThatShelf is a lightweight utility mod that adds a clean, highly-configurable HUD tooltip for Shelf blocks. Instead of opening an inventory to check your items, simply look at a shelf to see exactly what is inside.

Primary Features

Smart Item Detection

When looking at a shelf, the mod identifies the specific slot your crosshair is targeting and displays its contents instantly.

Triple Mode: If you prefer to see everything at once, you can enable Triple Mode in the settings to display all three shelf slots simultaneously.
Adjustable Spacing: You can use the "Gap" slider to fine-tune the distance between these three tooltips, whether they are stacked vertically or spread horizontally.

Live Configuration

Forget about restarting your game to change settings. Pressing "I" (the default, rebindable key) opens a specialized settings screen.

Visual Feedback: Because the settings menu is 100% transparent and usable while looking at a shelf, you can see HUD changes in real-time as you toggle options.
Dynamic Scaling: The "Scale" slider (0.25x to 3.0x) allows you to resize the tooltip based on your screen resolution.
Config Folder Access: A dedicated button in the menu opens your configuration folder instantly, making manual edits easy.

Intelligent Positioning

The HUD includes six anchor points: Top Left, Middle, and Right, and Bottom Left, Middle, and Right.

Chat Awareness: If you use a Bottom position, the tooltip will automatically jump to the Top whenever you open the chat bar so it doesn't block your typing.
XP Bar Safety: The Bottom-Middle position is pre-configured with a specific margin to sit safely above your experience bar and hotbar.

Content & Style

You have total control over what information is displayed on the HUD:

Data Toggles: Choose to show or hide item attributes, potion effects, mod names, and advanced technical info.
Amount Formatting: Display item counts in seven different positions, such as above the name, after the name, or relative to the item lore.
Color Overrides: The mod supports custom Hex codes, Minecraft color codes, and named colors for mod names, attributes, and more.
Transparency Mode: You can toggle the background box on or off to create a floating text effect for a more minimal UI.

Compatibility & Requirements

WTHIT Integration: Built-in compatibility prevents overlapping tooltips. WIITS tells WTHIT to hide its default block tooltip when looking at a shelf so only the item info is visible.
Requirements: Requires Minecraft 1.21.x, Fabric Loader, and Fabric API.
