The Pin Enhancer plugin improves Obsidian's pin functionality by preventing pinned tabs from being closed accidentally, such as through middle-click actions. It provides alternative commands to rebind standard hotkeys for closing tabs, ensuring pinned tabs remain secure while maintaining user flexibility. The plugin currently allows pinned tabs to be closed via context menu options, preserving an intentional way to manage them. This tool is ideal for users who frequently use pinned tabs and want added protection against accidental closures.
