Prevent Items From Being Quick Stacked
Understanding the Hotbar Exception
By default, Quick Stack Mod never transfers items from your hotbar—only from your main inventory. This is intentional: your hotbar stays untouched so you don't accidentally lose equipped tools or frequently-used items.
Keep Items in Your Inventory
If you want to prevent specific items from being quick stacked, simply keep them in your hotbar. Items in slots 1-9 will never be transferred, even when you use Quick Stack All.
For Other Items
Currently, the mod doesn't offer per-item blacklists or exceptions beyond the hotbar protection. If you want to keep certain items with you, move them to your hotbar before quick stacking.
Workflow Tip
Arrange your hotbar strategically: place tools, weapons, and frequently-used blocks in slots 1-9, then use Quick Stack All freely. Everything else will transfer, and your essentials stay safe.
