## Usability fixes (16/18 done)

Issues from hands-on testing of the deployed prod site (Feb 2025). 16 of 18 complete. The remaining 2 are tracked as features in the task list above (#16 variant refinement, #18 shipping costs).

## Roadmap

### Tier 1 — MVP (can take real orders and fulfil them)

1. ~~**Order management admin**~~ — ✅ Complete (02cdc81). Admin UI at `/admin/orders` with status filter tabs, streamed order table, and detail view showing items, totals, and shipping address.
2. ~~**Orders & fulfilment**~~ — ✅ Complete. Submit paid orders to Printify, track fulfilment status (submitted → processing → shipped → delivered), webhook-driven status updates with polling fallback, admin UI with submit/refresh actions.
3. ~~**Transactional emails**~~ — ✅ Complete. Plain text order confirmation (on payment via Stripe webhook) and shipping notification (on dispatch via Printify webhook + polling fallback). OrderNotifier module, 10 tests.
4. ~~**Default content pages**~~ — ✅ Complete (5a43cfc). Generic `ShopLive.Content` LiveView handles about + 3 policy pages (delivery, privacy, terms) via `live_action`. Rich text with list blocks, footer links updated, theme editor preview. 10 tests (575 total).

### Tier 2 — Production readiness (can deploy and run reliably)

5. ~~**Hosting & deployment**~~ — ✅ Complete. Alpine Docker image (131 MB), Fly.io config, release overlays, health check endpoint, hardcoded path fixes for releases. Observability: LiveDashboard in prod behind admin auth, ErrorTracker for exception capture, JSON structured logging, Oban/LiveView telemetry metrics, os_mon for CPU/disk/memory.
6. **Litestream / SQLite replication** — Litestream for continuous SQLite backup to S3-compatible storage. Point-in-time recovery. Simple sidecar process, no code changes needed, works with vanilla SQLite. For the hosted platform (Tier 5), evaluate [Turso](https://turso.tech/) (libSQL fork of SQLite) with embedded read replicas via [ecto_libsql](https://github.com/ocean/ecto_libsql) adapter — gives multi-node reads without a separate replication daemon, but adds a dependency on the libSQL fork.
7. ~~**CI pipeline**~~ — ✅ Complete. `mix ci` alias: compile --warning-as-errors, deps.unlock --unused, format --check-formatted, credo, dialyzer, test. Credo configured with sensible defaults. Dialyzer with ignore file for false positives (Stripe types, Mix tasks, ExUnit internals). 612 tests, 0 failures.
8. ~~**PageSpeed in CI**~~ — ✅ Complete. `mix lighthouse` task runs Google Lighthouse against the shop with configurable thresholds. Builds production assets (minified + digested + gzipped), waits for image variant cache, checks all 4 categories. Mobile: 99-100, Desktop: 97-100 across all pages. Unconditional gzip on Plug.Static.
9. **End-to-end & accessibility tests** — Wallaby browser tests for critical flows (browse → add to cart → checkout → order confirmation) with A11yAudit assertions baked into each test. Covers the happy path, key error cases, and WCAG 2.1 AA compliance in one pass. Wallaby drives a headless Chrome, A11yAudit wraps axe-core for automated a11y checks within ExUnit. Focus management, ARIA labels, keyboard navigation, colour contrast — all verified as part of the e2e suite rather than a separate audit.

### Tier 3 — Compliance & quality

10. **Privacy-respecting analytics** — Self-hosted, cookie-free analytics. Plausible, Umami, or a lightweight custom solution. No Google Analytics, no third-party tracking. GDPR-friendly by design.
11. **AGPL licensing & code hosting** — Currently AGPL-3.0. Decide on GitHub vs Codeberg vs self-hosted Forgejo. Set up proper LICENSE file, contribution guidelines, and release process.
12. **Security (Paraxial.io)** — Runtime application security monitoring for Elixir. Bot detection, rate limiting, vulnerability scanning. Evaluate whether it fits the self-hosted model.

### Tier 4 — Growth & content

13. **Page editor** — Database-driven pages with drag-and-drop sections. Extend the theme system to custom pages beyond the defaults. Replaces the static content pages from Tier 1 with editable versions. **Removes PreviewData usage from `content.ex`** (about, delivery, privacy, terms content blocks are currently hardcoded in PreviewData).
14. **Newsletter & email marketing** — Email list collection (signup forms). Campaign sending for product launches, sales. Can be simple initially (collect emails, send via Swoosh) or integrate with a service.
15. **Product page improvements** — Pre-checkout variant validation (verify Printify availability). Cost change monitoring/alerts. Better image gallery (zoom, multiple angles). **Product reviews system** to replace the hardcoded `PreviewData.reviews()` on the PDP template.

### Tier 5 — Platform vision

16. **Hosted platform** — Marketing/brochure site for SimpleShop as a service. Subscribe/sign-up flow. Multi-tenancy with per-tenant databases. Stripe Connect for customer shops (each merchant connects their own Stripe account via OAuth).
17. **Migration & export** — Let shop owners export their data (products, orders, customers, theme settings). Import from other platforms (Shopify, WooCommerce). Portable data as a selling point for the self-hosted story.
18. **Internationalisation (i18n)** — Multi-language support via Gettext (already in Phoenix). Currency formatting. RTL layout support. Per-shop locale configuration. **Note:** `ex_money`/`ex_cldr` are currently used *only* for `Cart.format_price/1` (a single GBP formatting call) but add ~13 MB to the release (ex_cldr 9.5 MB, digital_token 3.7 MB, ex_cldr_numbers, ex_cldr_currencies). Consider replacing with a simple `format_price/2` function that handles GBP/EUR/USD directly — all three use 2 decimal places and are trivial to format. Re-add `ex_money` later if proper locale-aware number formatting is needed (e.g., German `12.345,67 €`).
