MustardUI Helper is a Blender add-on designed to manage collections and object naming conventions. It provides tools for batch renaming, allowing users to automatically add prefixes to selected collections and rename objects based on their parent collection's name. The add-on also includes a function to remove specific words from object names to standardize nomenclature across a project.

The tool integrates directly with the MustardUI framework, enabling users to add selected collections as MustardUI outfits. Processing can be performed on collections selected in the view layer or via a UI list in the N-panel. It ensures that collections are included in the active view layer before executing renaming or integration operations.
