The Bookmark Dial – An Extension That Shows Thumbnails of Your Bookmarks
The Bookmark Dial is an extension for your browser. With it, you can add bookmarks to a folder. When you open a new tab the first time you will be presented with a list of all bookmarks and folders that have been added so far. You can drag and drop them to move the order.
When you open the popup window of a bookmark, you will see a preview of the webpage it was taken from. If you want to add a new item to the bookmark, you will be presented with the options of a bookmark dialog, allowing you to create a new item and add it to the folder.
