Pico Stackables

Pico Stackables lets you change how much every item and block stacks to, with full control through a friendly in-game editor — no file editing required.

Features

• Global multiplier — scale every stack size at once (e.g. ×2 turns a stack of 16 into 32, 64 into 128).
• Flat size mode — prefer a single number? Flip one switch to set every item and block to a fixed stack size, like 500 or 1000.
• Prevent item loss — a safety toggle (on by default) that never lets a stack size drop below its vanilla value, so changing your settings can't truncate and delete items from existing oversized stacks.
• Per-item / per-block overrides — click any entry, type an exact stack size, and Apply. It keeps that custom value and ignores the global setting (shown in yellow). Right-click to quick-toggle.
• In-game config dialog — type .picostackables to open a searchable, multi-column grid of every item and block in the game, including modded content, with hover tooltips and a live “which mode is active” indicator.
• Live preview — each entry shows original → new with the new value in green, updating instantly as you adjust the multiplier or flat size.
• Never lose your edits — the dialog shows when you have unsaved changes and asks before closing if you do. Settings are saved to disk and reload automatically every session.
• Clean list — tools and other durability items, creatures/NPCs, and internal placeholders are automatically left alone and hidden, so you only see things you'd actually stack.
• Works with other mods — applies to all registered blocks/items automatically, no configuration needed.

How to use

1. Install the mod and load a world.
2. Press Enter and type .picostackables to open the editor.
3. Pick a multiplier or flat size, fine-tune individual items if you like, and hit Save.

Notes

• Stack-size changes are applied on both the server and connected clients; on multiplayer, only server operators can save changes.
• A few mods that compute stack sizes dynamically in code may override the setting for their specific items.
