Fast Dial replaces "about:blank" page with a panel of thumbnails of your favorite sites. Click on an empty cell, assign a site URL, click OK – a thumbnail will be generated for a site. You can also add sites opened in browser or existing bookmarks by right-clicking them and choosing "Add to Fast Dial" from context menu.
By checking "Group" checkbox in thumbnail properties you can create groups of nested thumbnails.
