Toggle add-ons from the dashboard. New Add-ons panel — click a feature (semantic cache, persistent cache, fast routing, metrics auth, cost currency) to enable/disable it; the extension runs hr features … and restarts the router for you (local or Docker). Config-driven add-ons (per-key budgets, local model) show status + how to manage them. Also: tidier provider-table alignment (right-aligned numeric columns, cleaner multi-model rows).
