The File Hider plugin allows users to manage their file explorer visibility in Obsidian by hiding specific files and folders. With a simple right-click, users can choose to hide items, making them invisible in the file explorer by default. Hidden files and folders can be toggled for visibility through a dedicated command. The plugin also provides options to unhide items either directly from the file explorer or via a management tab in the settings. It integrates seamlessly with the interface and supports additional customization through plugins like Customizable Sidebar for quick access to toggle commands.
