SlotID Tooltip

by Aurick

SlotID Tooltip shows the slot ID in a tooltip when a player hovers over an inventory slot, which helps when a custom GUI makes individual slots hard to tell apart.

FabricClient-side onlyMIT-01.21.1 – 1.21.11

What it does

Hovering over a slot in an inventory screen displays its numeric ID as a tooltip. The display works in the Creative mode inventory as well as in survival menus. The mod is a simple Fabric addition that changes only what the client shows, so it has no effect on item handling or saved data.

It is most useful on servers that use custom GUI textures, where slots can look alike and their positions are hard to identify. Environment: only the client needs it; servers run without it. It is published for Fabric alone, with builds covering 1.21.1 – 1.21.11, and it is released under MIT-0 and is not open source.

Key features

  1. Slot ID tooltips

    Hovering over an inventory slot displays the numeric ID of that slot as a tooltip.

  2. Creative inventory support

    The tooltip also appears in the Creative mode inventory menu, not only in survival screens.

  3. Slot identification in textures

    Players can tell individual slots apart in custom GUI textures where the layout is otherwise hard to read.

A simple client-side Fabric mod that displays the slot ID in tooltips when hovering over inventory slots. This is particularly useful in servers with custom GUI textures where its difficult to indentify individual slots.
