"However, unlike Safari, single-clicking on the tab group in Camino will display all the pages (within that tab group) in tabbed pages (see Figure 14). "

You can do this in Safari as well by doing the following:
bookmarks>>show all bookmarks
Then tick the "auto-tab" box

After doing this, the folder (mine is on my menu bar) will have a little square next to it rather than a triangle. When you single click on the name, all bookmarked pages get opened as tabbed pages.
