AutoBlockRefiller

Never run out of blocks mid-build again. When placing blocks empties your hotbar slot (or offhand) and more of the same block are in your inventory, a fresh stack slides into the empty slot a moment later. Silent and automatic.

• Refills only blocks, only into slots that are actually empty
• Searches the main inventory first, never touches armour or offhand stock
• Covers both hands: selected hotbar slot and offhand
• Requires Mycel 1.2.1 or newer: install it alongside this mod

Configuration

config/autoblockrefiller.json (or the mod menu screen):

• enabled (default true): master switch
• searchHotbar (default false): also take refills from other hotbar slots

Reload live with /mycel reload autoblockrefiller, or change values without restarting via /mycel set autoblockrefiller <key> <value>.
