SimpleMiner

A chain-mining mod.

What it does

Hold a key, mine a block, and everything connected to it goes too.

• Undo Every chain mine gets recorded.(If the server allows it) Open a GUI, pick a record, and the whole thing gets reverted — blocks restored, items returned to your inventory.
• Per-player max size. You can set your own limit (or leave it at -1 to follow the server).
• Block family matching. Instead of "only the same block", you can define families like minecraft:coal_ore,minecraft:deepslate_coal_ore or #minecraft:base_stone_overworld. Supports ! to exclude things.

Shapes

Shape	What it does
Shapeless	Mining matching squares that are connected to the pointing squares.
Linear	Straight line along your view direction. Width and height adjustable.
FullChunk	Scans whole chunks within a radius. X and Z radius configurable separately.

Strategies

Both block breaking and item collection have selectable strategies. You can change them in the config without restarting the server.

Undo

Every chain mine creates an undo record. Open the undo list with Ctrl + Z.
