Marker Manager is an add-on that expands the capabilities of Blender's timeline markers. It introduces a dedicated list view panel for all timeline markers, providing a clearer overview of scene annotations. The panel includes search, filtering, and a tagging system to quickly locate specific markers and jump to their corresponding frames.

The tool allows users to import and export markers as JSON files, enabling the transfer of marker data between different blend files or external software. It also includes utility functions like rendering the specific frame of a marker with a single click and automatically binding cameras to markers if their names match.
