What's new

1.1.0

✨ New Features

  • Left-click to open control panel — hold the Tunnel Tool and left-click anywhere to open the panel remotely (no need to walk to the block).
  • MTR-style preview track — thick yellow track band connects block tops from Start to End; follows the crosshair while holding the block.
  • Align hint — green message shows when your crosshair block is in line with the start point (can be used as the end point).
  • Middle-click picker (format brush) — hold the Tool and middle-click any block to set it as the wall block.
  • Scroll wheel — hover over the Width/Height boxes to adjust values (1–32).

🛠 Improvements

  • Underwater tunnels now excavate water/lava and auto-seal the shell (ends are sealed to keep water out).
  • Tunnel mouth is a perfect rectangular frame (fixed missing corner blocks).
  • Interconnected/random tunnel blocks in the same dimension share the same config.
  • Auto-clear Start/End points after digging (config persists otherwise).
  • Width/Height edit boxes can now be cleared and re-entered (no more stuck values).

🐛 Fixed

  • Fixed sync deadlock preventing Start/End from being set the first time.
  • Fixed tunnel auto-fill on open terrain not working in some cases.
  • Fixed oversized UI panel (compact layout, centered).
