The Note Linker with Previewer plugin enhances your Obsidian workflow by automating the process of finding and linking related notes across your vault. It uses a markdown parser to ensure links are placed only in valid contexts, excluding areas like code or LaTeX blocks. Features include caching for efficient performance, the ability to link an entire vault or a single note, and commands for identifying invalid notes and resetting the cache. This plugin is especially useful for maintaining well-structured and interconnected notes while avoiding issues caused by improper formatting.
