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.
