The Checkbox Autochecker plugin keeps parent and child checkboxes in sync, making task management inside Markdown lists far smoother. It can automatically mark a parent as complete when all its children are checked, or cascade changes downward when toggling the parent. Three propagation modes - Loose, Partial Strict, and Strict - give you control over how aggressively changes flow, whether only syncing upward or overwriting all children. It works instantly while typing, supports deeply nested lists, and respects standard Markdown formatting, so there's no lock in.
