The Icon Shortcodes plugin allows users to quickly insert emoji and custom icons into their Obsidian notes using intuitive shortcodes. It supports popular icon libraries like Unicode Emoji, Lucide, Font Awesome, and Remixicon, along with user-uploaded custom icons in formats such as PNG, JPG, SVG, and GIF. Icons can be inserted via a simple search-based suggester, with optional fuzzy search for better discovery. Users can manage their custom icon collections, rename, delete, or back up icon packs as needed. Custom CSS can be used to style icons, enabling changes to color, size, and appearance. The plugin also features an API, allowing developers to integrate its functionality into other plugins.
