Site Group

Site groups allow you to define a collection of web sites as a group. For example, you can put together a bunch of news sites as a group and open them every morning with a single click. You can create as many groups as you want. You can also organize the groups into subfolders like the way you organize regular bookmarks. You can even include one or more auto-login entries inside a site group.

Here is a screenshot of the Groups menu inside the web browser:
