Bug Fix: Resolved an issue where right-clicking a filled square (■) or left-clicking an "X" mark would incorrectly consume an "Undo" count even if no action was performed.
New Options: Added toggles to display the following indicators:
Mistake Counter: Tracks incorrect fills.
Remaining Moves: Displays how many moves are left.
Quality of Life Improvement: Added an Auto-Fill feature that automatically places "X" marks in the remaining empty spaces of a completed row or column.
