The Path Title plugin enhances the visibility of file paths in Obsidian by displaying the full path of the current file alongside its name. It allows users to customize the appearance of the path, including font size adjustments for better readability. Advanced settings enable path modifications, such as exact path or folder replacements, text replacements, and regular expression-based transformations. These features help streamline file organization and improve navigation, making it easier to manage and locate files within complex folder structures.
