Bookmark Toolbar Separator

My favorite way to use bookmarks is the bookmark bar. I usually don't have any folders and I usually only use bookmarks for top level domains such as [drive.google.com](drive.google.com). And my favorite way to name my bookmarks is with no name! This leaves the fav.ico as the only indication of where the bookmark takes you. VERY ATHSTETIC. The only issue is with 20 or so favicons there was no way to add separation between different groups of icons. A github pages with a blank favicon would do the trick.
