The Custom window title plugin enhances the Obsidian experience by displaying the current open note in the window title, allowing for better context while switching between applications. This plugin is particularly useful for those tracking application usage or managing multiple tasks, as it offers easy identification of the current note. Additionally, the plugin provides templating options, enabling users to customize the window title with variables like filename, filepath, vault, or workspace. It also supports frontmatter, allowing dynamic updates based on file metadata, further improving workflow efficiency and context-switching.
