The Note Chain plugin helps users organize their notes in a sequential order within Obsidian, creating a structured workflow for managing ideas. It allows users to link notes through metadata fields, establishing relationships such as previous and next notes to create a linear structure. The plugin offers commands to easily create, insert, and reorder notes in a chain, enhancing note management for projects, articles, or books. Users can also automate note chain organization within folders and sort files accordingly in the file explorer. Additional features include integration with popular Obsidian plugins like Dataview and Templater, enabling efficient workflow automation and tracking.
