The Advanced Note Composer plugin extends the functionality of Obsidian's core Note Composer plugin by addressing common limitations during note merging and content extraction. It intelligently updates relative links when content is moved between files, preventing broken links that usually require manual fixing. Additionally, it handles invalid characters in titles by either sanitizing them or storing the original form in note aliases or frontmatter titles for better compatibility with quick switcher and metadata-based workflows. This plugin is especially useful for users who regularly restructure their notes and want a smoother, error-free experience.
