The Mermaid Icons plugin fixes Font Awesome icon rendering in Mermaid diagrams and extends support to additional icon sets. While Mermaid natively supports Font Awesome syntax, the icons don't render properly in Obsidian without this plugin. It loads the necessary stylesheets and fonts. Beyond fixing Font Awesome, it bundles popular icon sets like SVG Logos and Lucide icons letting you use them with custom prefixes (`logos:icon-name`, `lucide:icon-name`). A fuzzy search modal triggered by `Cmd+Shift+m` helps you quickly find and insert icons.
