Player Move Detector
A mod that detects player movement with a mark after pressing a hotkey.
Guide
Press "X" (default) to enable movement detection. This can be changed in the control settings.
When enabled:
- If a player stands still, a green mark is shown above their name.
- If they move, a red mark will instead appear above their name.
Pressing the hotkey again will remove the movement mark above the player's name.
