The Note ID plugin helps structure and organize notes in Obsidian using an ID-based system, ideal for Zettelkasten-style note-taking. It arranges notes in alphanumeric order by their assigned `id` property, allowing users to track thought progression and identify clusters of related ideas. The plugin simplifies creating new notes by automatically generating sequential or branching IDs while keeping filenames clean. A dedicated table of contents view highlights key notes marked with a `toc` property, providing a structured navigation experience. Users can customize the ID hierarchy, manage folders for inclusion or exclusion, and configure note indentation.
