 | **Show Skip button**         | Use this to show or hide the **Skip** action for annotators. |
 | **Allow empty annotations** | This determines whether annotators can submit a task without making any annotations on it. If enabled, annotators can submit a task even if they haven't added any labels or regions, resulting in an empty annotation. |
 | **Show the Data Manager to annotators** | When disabled, annotators can only enter the label stream. When enabled, annotators can access the Data Manager, where they can select which tasks to complete from the Data Manager list. <br /><br />However, some information is still hidden from annotators and they can only view a subset of the Data Manager columns. For example, they cannot see columns such as Annotators, Agreement, Reviewers, and more. |
-| **Reveal pre-annotations interactively** | When enabled, pre-annotations are not automatically displayed to an annotator. Instead, annotators can choose when to reveal these pre-annotations as they work on the task, providing them with the opportunity to first assess the image or text without the influence of the model's predictions. |
+| **Reveal pre-annotations interactively** | When enabled, pre-annotation regions (such as bounding boxes or text spans) are not automatically displayed to the annotator. Instead, annotators can draw a selection rectangle to reveal pre-annotation regions within that area. This allows annotators to first review the image or text without being influenced by the model’s predictions. Pre-annotation regions must have the attribute `"hidden": true`. <br /><br />This feature is particularly useful when there are multiple low-confidence regions that you prefer not to display all at once to avoid clutter. |
 | **Annotators must leave a comment on skip** | When enabled, annotators are required to leave a comment when skipping a task. |
