The dragMoveEvent method calls dragEnterEvent for every mouse movement during a drag operation, which repeatedly validates the same URLs. Consider caching the validation result or implementing a more efficient approach that doesn't re-evaluate the URLs on every move event.

| # Use an empty string for unbound txt paths so os.path functions don't error. |

The comment mentions 'os.path functions don't error' but this change affects the logic in load_data() method which checks for falsy values. The comment should clarify that this change enables consistent falsy checking rather than preventing os.path errors.

| # Use an empty string for unbound txt paths to enable consistent falsy checking (e.g., in load_data()). |
