Bone Manager is an addon designed to streamline rigging workflows by centralizing armature controls. It provides a suite of bone collection tools that allow users to select, move, lock, and assign colors to bones directly from the interface. The tool includes a dynamic panel builder for creating custom property and modifier layouts, alongside features for managing constraint presets and custom properties. Users can quickly toggle deform properties for debugging and export their customized Rig UI to a standalone script for use in other projects.
