The Link Favicons plugin allows users to view favicons for linked websites without requiring custom CSS. It works seamlessly with various plugins, including Admonition and RSS Reader. The plugin offers a range of icon providers, including Google, DuckDuckGo, and Favicon Grabber, each with its own set of features and limitations. Users can also overwrite icons for specific domains or URI schemes using the Icon Shortcodes plugin. Additionally, users can disable favicons on specific links by adding `|nofavicon` to the link alias. For designers, styling options are available through CSS snippets, while developers can integrate the plugin with their own code using the renderMarkdown method.

The Note Favicon plugin enhances note visibility in Obsidian by displaying a favicon next to note titles in the file tree. It extracts a URL from the frontmatter and fetches the corresponding favicon, allowing for quick visual identification of notes. Users can also embed base64-encoded images for greater customization without relying on external sources. The icons update dynamically when metadata is modified, ensuring an up-to-date representation of note associations.
