Site logo asks each site for its own favicon — no middleman, but some sites don't publish one at the standard path and keep their initials. Google service almost always resolves, at the cost of Google seeing the list of domains. Initials only makes no outside requests at all. The built-in apps always carry their own icon.
The icon Chrome keeps when you bookmark this page. Empty for the site logo.
.html is the format Chrome, Firefox, Safari and Edge expect when importing: every section arrives as a folder and every item keeps its name. In Chrome: Bookmarks → Import Bookmarks and Settings → Bookmarks HTML File.
Format — plain Markdown: # Title names the desk, each ## Section opens a section, and each - [Name](link) is one square. A link pointing at a page on this site comes back in as an app, icon and all. Any other line is ignored.
