The Completed Tasks plugin automatically moves checked-off tasks to the bottom of their list, helping keep notes clean and focused. It runs in the background and checks for changes every few seconds to reorder completed items without interrupting your writing flow. It supports root-level task lists and ensures that subtasks stay attached to their parent task during sorting. The plugin also works well with the popular Tasks plugin, though it doesn't depend on it. With minimal setup and automatic operation, it's ideal for users who frequently work with to-do lists and want a tidy, distraction-free structure as they complete tasks.
