Overview

The Timeline Marker Groups add-on for Blender provides a powerful solution for organizing and managing timeline markers. Create named groups of markers, toggle visibility, export/import configurations, and streamline your animation workflow—all from a convenient panel in the Dope Sheet Editor.

Key Features

✔ Group Management – Save sets of timeline markers as reusable groups
✔ Visibility Toggle – Show/hide entire marker groups with one click
✔ Import/Export – Save groups to JSON files for sharing or backup
✔ Camera Binding Support – Preserve camera assignments in marker groups
✔ Non-Destructive Workflow – Edit groups without affecting existing timeline markers
✔ Batch Operations – Quickly select/deselect all markers

How It Works

1. Save Marker Groups – Select markers in the timeline and save them as named groups

2. Load Groups – Restore marker sets with their original frame positions and camera bindings

3. Toggle Visibility – Temporarily hide groups without deleting them

4. Export/Import – Share marker configurations between projects or backup your setups
