Add a feature that goes beyond CRUD

[robert-7]

Summary

Right now the app is registration + login + enroll in course — the absolute baseline of a tutorial. Adding one non-trivial feature transforms it from "I can follow instructions" to "I can build things."

Feature Ideas (Pick One or More)

Feature	Complexity	What It Demonstrates
Search/filter courses by term, credits, or keyword	Low	Query building, UX thinking
Admin panel for managing courses (add/edit/delete) with role-based access	Medium	Authorization, RBAC, form design
User dashboard with enrollment history	Low-Medium	Aggregation pipelines, data presentation
Email confirmation on registration (via Flask-Mail)	Medium	Async workflows, external service integration
Rate limiting on API endpoints	Low	Security awareness, middleware patterns
Export enrollment as CSV or PDF	Low	File generation, content-type handling
Background task for email notifications on enrollment (Celery + Redis)	High	Task queues, distributed architecture

Tasks

• Choose a feature from the list above (or propose your own)
• Implement it with clean, tested code
• Update the README to highlight the new feature
• Add tests for the new functionality

Why This Matters

The difference between a tutorial project and a portfolio project is originality. One feature that wasn't in the tutorial demonstrates independent problem-solving and creativity — exactly what interviewers are looking for.

Priority

P2 — Strengthens it | Effort: Large (varies by feature)
