Bucket Replenisher
A simple and lightweight mod to automatically swap empty buckets in your hand for new ones in your inventory
I don't know my version or loader

Auto Bucket Swap Never dig through your inventory for the next water bucket mid-build again.
You place water, end up with an empty bucket, open your inventory, drag down the next full bucket, close the inventory — and repeat that for every single block. This mod does it for you.
The moment you place a fluid, it scans your whole inventory for the next full bucket of the same fluid and swaps it into your hand. The empty bucket goes into the slot the full one came from. You are instantly holding a full bucket again and just keep building.
What it's good for
Building on DonutSMP — water pools, farms, large terraforming projects: anywhere you empty buckets by the dozen, you save an inventory detour on every single placement Lava work — lava trenches, mob grinders, decorative lava Redstone & farms — place water streams precisely without breaking your building flow Terraforming — fill lakes and rivers without losing your rhythm What it does
Pulls full buckets from your entire inventory, hotbar and off-hand included Never gets in the way: no matching bucket → behaves exactly like vanilla Water and lava kept separate — a water bucket never accidentally pulls lava Vanilla-style settings menu, freely rebindable key (default: K) Client-side only, 11 KB, works on vanilla servers Installation: Fabric API + autobucketswap-1.0.0.jar into mods, restart.
