Wan's ShapeMiner Add-on 1.21+

When you want to dig not block by block, but in entire layers—it's time to switch to heavy equipment. That's exactly what the mod Wan's ShapeMiner is for. The addition turns ordinary mining into absolute enjoyment—you'll be able to break 9, 25, and even 49 blocks at once in Minecraft Bedrock.

Set the shape, depth, and width of your excavation: areas of size 3x3, 5x5, 7x7, or deep tunnels. To change modes, you need to Sneak. The current mode and tool durability are displayed above the quick access bar while using it. Enchantments also work.
