The Todoist Completed Tasks plugin allows users to seamlessly integrate their completed tasks from Todoist into Obsidian notes. By specifying start and end segments in a note, users can fetch completed tasks for today, the past N hours, or based on custom date ranges. The plugin supports customizable prefixes and postfixes for tasks, making it compatible with other task management tools like Obsidian Tasks. With features designed to enhance task tracking within notes, it provides a streamlined way to manage completed Todoist tasks directly in Obsidian.

The Todo.txt Mode plugin adds robust support for the todo.txt task format, blending plain text task management with enhanced visual and functional features. It highlights task elements such as priorities, projects, contexts, due dates, and completed status using colour-coded decorations, which can be further customised via the Style Settings plugin. Users can move completed tasks to a dedicated file and sort tasks by priority, project, context, or due date. A boundary marker can be defined to exclude parts of the file from sorting. This plugin is ideal for those who prefer the todo.txt methodology but want smoother visual feedback and better task organisation within their notes.

The Completed Area plugin streamlines task management in Obsidian by moving completed to-do items into a designated 'Completed' section. Users can toggle this feature through a sidebar icon or a default shortcut (`Control + Enter`). The plugin allows customization of the completed area's header level (h1 to h6) and header name, with defaults set to h2 and 'Completed,' respectively. Users can also choose to disable the sidebar icon and rely solely on commands for a cleaner interface.
