Flexible Renamer is an addon that provides batch renaming capabilities for elements within a Blender scene. The tool operates from a dedicated sidebar panel, allowing users to apply structured naming conventions across multiple selected items simultaneously. It includes standard text operations like adding prefixes and suffixes, overriding base names, find-and-replace functionality, and auto-numbering with custom start and step values.

The expanded version of the tool extends renaming support beyond objects to include meshes, materials, images, collections, and armature bones. It also introduces additional string manipulation features, such as trimming characters from the beginning or end of existing names and utilizing a unified global auto-numbering system across different data types.
