The Simple Disguise plugin provides an easy way to obscure the content in your editing area, making it less visible to others in public spaces. By toggling a button in the sidebar, users can switch between normal and disguise modes. The plugin alters the background and text colors of the editor using CSS to reduce the clarity of displayed content. While it does not support reading mode or command-based controls, users can manually adjust styles by editing the plugin's CSS file. This tool is ideal for enhancing privacy during note editing in shared environments.
