The Header navigation plugin enhances navigation within Obsidian notes by allowing users to move quickly between headers and toggle their visibility. Users can fold and unfold headers to streamline the view of large documents, making it easier to focus on specific sections. The plugin offers command palette actions for navigation and folding, which can be assigned to hotkeys for faster access. This tool is inspired by the header navigation features found in Emacs org-mode, providing a familiar experience for those accustomed to structured document navigation. It supports efficient movement through long-form content, helping users stay organized and maintain a clear overview of document structure.
