+### 🔄 Advanced Query Features (Filtering, Sorting, Pagination)
+
+The `list` action endpoint now supports advanced query parameters:
+
+| Parameter    | Type    | Description                                                                                       |
+|--------------|---------|---------------------------------------------------------------------------------------------------|
+| `filter`     | string  | Filter rows by column values. Format: `filter=col1:value1,col2:value2`. Use `%` for wildcards.    |
+| `sort`       | string  | Sort by columns. Comma-separated. Use `-` prefix for DESC. Example: `sort=-created_at,name`       |
+| `page`       | int     | Page number (1-based). Default: `1`                                                               |
+| `page_size`  | int     | Number of rows per page (max 100). Default: `20`                                                  |
+
+**Examples:**
+
+- `GET /index.php?action=list&table=users&filter=name:Alice`
+- `GET /index.php?action=list&table=users&sort=-created_at,name`
+- `GET /index.php?action=list&table=users&page=2&page_size=10`
+- `GET /index.php?action=list&table=users&filter=email:%gmail.com&sort=name&page=1&page_size=5`
+
+**Response:**
+```json
+{
+  "data": [ ... array of rows ... ],
+  "meta": {
+    "total": 47,
+    "page": 2,
+    "page_size": 10,
+    "pages": 5
+  }
+}
+```

 ## 🗺️ Roadmap
 
-- RESTful route aliases (`/users/1`)
-- OAuth2 provider integration
-- More DB support (Postgres, SQLite)
-- Pagination, filtering, relations
+- Relations / Linked Data (auto-join, populate, or expand related records)
+- API Versioning (when needed)
+- OAuth/SSO (if targeting SaaS/public)
+- More DB support (Postgres, SQLite, etc.)
+- Analytics & promotion endpoints
