Watson
by Annevdl29
Watson is a Client-side only utility mod that draws LogBlock, CoreProtect and Ledger query results as 3-D boxes, labels and vectors in the world.
What it does
Watson displays logs from LogBlock, CoreProtect and Ledger in three-dimensional space. Each individual edit appears as a wireframe box, edits on ore blocks are grouped into deposits with a number shown in the scene, and vectors connect edits in the order they happened. Text annotations can be placed in 3-D space as well. Annotations and edits are written to files and reopened later, so an investigation can resume.
The mod is aimed at moderation and investigation work on servers that record block changes. Watson also provides commands to teleport to deposits, and a simple built-in calculator works out stone-to-diamond ratios. Some features make tasks such as observing chat or managing screenshots a little easier. The main menu opens with L, and the config menu with L then C.
Watson requires MaLiLib. It is published for Fabric and Quilt for 1.16.2 – 1.21.4, and the latest file is for 1.21.4. The code is open source under the MIT License.

Ore deposit tracking

Who it’s for: Server moderators and staff who check block logs from LogBlock, CoreProtect or Ledger, and players who want a visual record of edits in their own world.
