Attribute Manager provides a central, spreadsheet-style interface within the 3D View sidebar for viewing and editing mesh and object data. Users can modify values directly in rows and columns instead of navigating through multiple property panels. It supports multiple editing modes including vertex, edge, face, face corner, and object levels.

The add-on features batch operations for applying single values across multiple rows or unifying attributes efficiently. It integrates expression support, allowing users to apply mathematical operations across rows using Python's native math module. The tool limits specific attribute categories by object type, filtering for meshes, lights, cameras, and empties. Additionally, it offers a modifier mode for copying properties across modifiers of the same type, along with visual overlay aids like viewport mesh indices and gradient vertex weights.
