+# Roadmap
+
+## Now
+
+- **Notification and subscription system** - Subscribe to courses and get alerts on seat availability, waitlist movement, and detail changes (time, location, professor, seats). DB schema exists.
+- **RateMyProfessor integration** - Show professor ratings inline with search results and course details.
+- **Professor name search filter** - Filter search results by instructor. Backend code exists but is commented out.
+- **Subject/major search filter** - Search by department code (e.g. CS, MAT). Also partially implemented.
+- **Autocomplete for search fields** - Typeahead for course titles, course numbers, professors, and terms.
+- **Test coverage expansion** - Broaden coverage with pure function tests (term parsing, search parsing, job types), session/rate-limiter tests, and more DB integration tests.
+- **Web course search UI** - Add a browser-based course search interface to the dashboard, supplementing the Discord bot.
+
+## Soon
+
+- **Smart time-of-day search parsing** - Support natural queries like "2 PM", "2-3 PM", "ends by 2 PM", "after 2 PM", "before 2 PM" mapped to time ranges.
+- **Section-based lookup** - Search by full section identifier, e.g. "CS 4393 001".
+- **Search result pagination** - Paginated embeds for large result sets in Discord.
+- **Multi-term querying** - Query across multiple terms in a single search instead of one at a time.
+- **Historical analytics** - Track seat availability over time and visualize fill-rate trends per course or professor.
+- **Schedule builder** - Visual weekly schedule tool for assembling a conflict-free course lineup.
+- **Professor stats** - Aggregate data views: average class size, typical waitlist length, schedule patterns across semesters.
+
+## Eventually
+
+- **Degree audit helper** - Map available courses to degree requirements and suggest what to take next.
+- **Dynamic scraper scheduling** - Adjust scrape intervals based on change frequency and course count (e.g. 2 hours per 500 courses, shorter intervals when changes are detected).
+- **DM support** - Allow the Discord bot to respond in direct messages, not just guild channels.
+- **"Classes Now" command** - Find classes currently in session based on the current day and time.
+- **CRN direct lookup** - Look up a course by its CRN without going through search.
+- **Metrics dashboard** - Surface scraper and service metrics visually on the web dashboard.
+- **Privileged error feedback** - Detailed error information surfaced to bot admins when commands fail.
