Thanks! Can you please give me some idea about what enhancements you want so that I can work accordingly to what you prefer. @Hrishikesh-Dalal

• Question Categories + Difficulty: Add a select (category) and radio buttons (difficulty). Filter a larger question bank loaded from JSON. This lets users tailor quizzes (e.g., Math / Geography, Easy / Hard) and increases replay value with minimal UI overhead.

• Shuffle & Session Settings: On start, randomly shuffle both questions and answer choices; let user choose number of questions (e.g., 5 / 10 / All). Use a pure Fisher–Yates shuffle and a seed (optional) for reproducible “daily” quizzes.

• Timer & Progress Feedback: Implement a per-question countdown (e.g., 20s) plus a visual progress bar (current / total). Auto-advance or mark unanswered when time expires. Shows urgency and builds engagement, while progress reduces abandonment.
