Stardew Chest Buttons

Chest Buttons recreates two of Stardew Valley's most-loved chest-UI buttons in Minecraft. Open any chest, double chest, barrel, or shulker box and two icon buttons appear on the left side of the screen:

• Add to Existing Stacks  - for every item type the chest already holds, instantly moves all your matching items into it. It tops up existing stacks first, then starts new stacks in any empty slots, so a chest that already has some cobblestone will swallow your entire cobblestone haul in one click. Item types the chest *doesn't* already contain are left in your inventory - it never dumps unrelated items in.
• - Organize  - consolidates partial stacks and sorts the entire chest neatly by item.

No more dragging items one stack at a time - deposit and tidy a chest in a single click.

Multiplayer

Fully server-aware. The buttons are drawn client-side, but every item move is validated on the server, so it's completely cheat-safe. The mod is required on both the client and the server; if only the client has it, the buttons simply won't appear.
