Feature Request

Enhance the graph in the macOS pop-up so that users can drag their mouse pointer across a specific time window. When a range is selected, the tool should calculate and display the average stats for that selected window. This will help users analyze their typing performance for any custom time interval interactively.

Acceptance Criteria:

• User can click and drag on the graph to select a time window.
• The tool visually highlights the selected range.
• The average stats (e.g., WPM, accuracy, etc.) for the selected window are calculated and displayed clearly in the pop-up.
• Works smoothly within the macOS pop-up interface.

Additional Notes:

• Provide visual feedback while dragging (e.g., shaded area).
• Indicate average stats in a dedicated section or tooltip after selection.
• Should not interfere with other pop-up functionalities.
