Outliner Pro is an add-on that introduces a set of organizational tools to Blender's Outliner. It provides operators for moving objects and collections to the active collection directly from the viewport or the outliner interface. The tool includes support for moving full hierarchies and children, and allows users to create new collections and immediately assign objects to them without navigating the outliner tree.

Additionally, the add-on includes several synchronization features. Users can match object viewport colors to their parent collection's assigned color, which is visible in both shaded and wireframe modes. An auto-scroll function keeps the active object centered within the outliner view. Another tool matches viewport visibility settings to render visibility, ensuring hidden objects do not appear in final renders. The toolset also features a batch renaming function that automatically renames objects based on their parent collection.
