About

A client-side Fabric mod for Minecraft *.21.4 that helps players monitor their traps. Mark blocks with U or Shift+U, organize them into named groups, and receive instant chat alerts when other players step on or above marked blocks. Features include customizable colored outlines visible within 20 blocks, per-group settings, a comprehensive settings GUI, and persistent JSON-based configuration. Detection runs continuously in the background regardless of visual settings.
