  • Right-click a square to instantly remove the piece on it.
  • Use the 'White/Black to Move' buttons to set the turn for the position.
  • Click 'New Game' to reset to the starting position, or 'Clear Board' to empty the board.
• Saving & Loading:
  • In the "Saved Positions" section, type a name and click 'Save' to store the current position.
  • Select a saved position from the dropdown and click 'Load' to view it.
  • Click 'Del' to permanently remove the selected saved position.
• Import & Export: You can back up your saved positions to a file. 'Export' saves all positions to a `fishyfen_games.json` file. 'Import' allows you to load positions from such a file. Check "Overwrite" to replace existing positions that have the same name.
