 The plugin template provides new APIs for bootstrap plugins. We have two reasons to use these APIs, instead of the `createElement/createElementNS`:
 
-- In bootstrap mode, plugins have to clean up all UI elements on exit (disable or uninstall), which is very annoying. Using the `createElement`, the plugin template will maintain these elements. Just `unregister` on exit.
-- Zotero 7 requires createElement()/createElementNS() → createXULElement() for remaining XUL elements, while Zotero 6 doesn't support `createXULElement`. Using `createElement`, it switches API depending on the current platform automatically.
+- In bootstrap mode, plugins have to clean up all UI elements on exit (disable or uninstall), which is very annoying. Using the `createElement`, the plugin template will maintain these elements. Just `unregisterAll` at the exit.
+- Zotero 7 requires createElement()/createElementNS() → createXULElement() for remaining XUL elements, while Zotero 6 doesn't support `createXULElement`. The React.createElement-like API `createElement` detects namespace(xul/html/svg) and creates elements automatically, with the return element in the corresponding TS element type.
 
-There are more advanced APIs for creating elements in batch: `creatElementsFromJSON`. Input an element tree in JSON and return a fragment/element. These elements are also maintained by this plugin template.
+```ts
+createElement(document, "div"); // returns HTMLDivElement
+createElement(document, "hbox"); // returns XUL.Box
+createElement(document, "button", { namespace: "xul" }); // manually set namespace. returns XUL.Button
