-Additionally, you can define a special `params` dictionary. In it, the `display_name` key is used to define the displayed name of the extension in the UI, and the `is_tab` key is used to define whether the extension should appear in a new tab. By default, extensions appear at the bottom of the "Text generation" tab.
+Additionally, you can define a special `params` dictionary. In it, the `display_name` key is used to define the displayed name of the extension in the UI. The `is_tab` key is deprecated and it is better to write UIs in `def ui_tab():` instead, but is still supported if the UI is created in the deprecated `def ui():`
