Easy Exchange（简易替换）
by raven_777
Replacing broken blocks with the block held in the off-hand is what this mod does, which suits large building and terrain projects.
What it does
While a mining tool is held in the main hand and a replacement block sits in the off-hand, pressing the R key turns on automatic replacement. Each block mined is then swapped for the off-hand block, so a wall or terrain can be reshaped without placing blocks one at a time. Pressing R again turns the function off. When the off-hand stack runs out, the inventory is refilled from matching blocks, keeping the process running.
The mod is aimed at large-scale building projects and terrain modification, where fast block swapping saves repeated manual steps. Installation covers the server and each player's game. Files are published for Fabric, Forge and NeoForge, covering 1.20.1 and 1.21.1, with 1.0.0 as the latest version on each loader. Architectury API is required on every loader. FTB Ultimine Cobblemon Compat is required as well. The mod is not open source and is released under All rights reserved.
Key features
Automatic block replacement
Blocks broken with a mining tool are replaced at once by the block held in the off-hand.
R key toggle
Pressing R switches automatic replacement on or off, so the function runs only when it is wanted.
Off-hand auto-refill
When the off-hand stack is used up, the inventory refills it, so the replacement does not stop mid-project.
Terraforming workflow
Mined terrain is reshaped by swapping blocks, which speeds up large-scale terrain edits.

Use cases
Who it’s for: Builders and terrain editors working on large projects in single-player worlds or on multiplayer servers that allow the mod. Players who only need occasional block placement will find little use in it.
How it compares
Create Ultimine is open source under the GNU General Public License v3.0 only and is published for Forge and NeoForge across 1.20.1 – 1.21.1, so it has no Fabric build. Stack Refill runs on Fabric, Forge, NeoForge and Quilt for 1.16.5 – 26.3 under All rights reserved, and it refills stacks without the block swap that this mod performs. Automatic replacement is open source under the MIT License and is published for Fabric and Forge for 1.20 – 26.1.2, while this mod is not open source.
