+#### Disabling Editor Features
+
+You can also disable specific features inside the PDF Editor (e.g., redaction, annotations, forms) without disabling the entire editor tool. Add `editorDisabledCategories` to your `config.json`:
+
+```json
+{
+  "editorDisabledCategories": ["redaction", "annotation-stamp"]
+}
+```
+
+<details>
+<summary>Full list of editor categories</summary>
