1. Window Mode Fix
Standard: Fixed a bug where switching from full-screen to windowed mode caused the mouse cursor position to become misaligned (offset slightly to the bottom-right).
2. Undo/Redo Logic Fix
Standard: Fixed a bug where using Undo or Redo wouldn't work correctly when filling "0" or "20" (max) lines if those lines already contained some filled cells.
3. UI/Color Feedback
Standard: In Color mode, the background color of a determined line will now change when you hover over it with the mouse.
4. New Option Added
Standard: Added a new setting to "Options": In addition to auto-filling lines that are 0 or the maximum size, you can now choose to auto-fill any determined lines.
