Petite Inventory

When a layout is enabled for a container, items occupy the rectangular footprints configured for them. Items of matching type stack and transfer under configurable replacement and stacking rules, and moving one item over another can replace the conflicting item in the target area. Shift quick transfer searches for an empty area that fits the held item, while the hotbar is left out by default so it behaves as in vanilla. After picking up a non-square item, pressing R flips the current item instance, and the mouse wheel rotates its footprint.

The layouts are defined through rule files, which are generated on first launch with default rules. Rules can match by item identifier, by tag or by exact component data, and they reload with the reload command and take effect immediately. A visual editor, toggled with petiteinventory edit, lets users resize item borders by dragging an edge or corner, change background colors from a preset palette, and batch-edit footprints with a selection drag. The player inventory is controlled separately, so its balance can be set on its own. Players can copy a screen identifier with the U key and add it to the configuration to enable a layout for another container.
