Todo is a task management add-on that integrates directly into Blender, allowing users to track project progress within their files. The tool offers both a kanban board layout and a traditional list view for organizing tasks. Users can assign statuses, set priorities, and monitor completion through progress bars. The add-on includes features for linking external URLs, filtering by status, and searching tasks by name. Task information can be displayed directly in the 3D viewport, with customizable text size, color, and positioning stored in the preferences. Additionally, task lists can be exported and imported to transfer workflows between different Blender scenes.
