IE7 has tabs. It's tabs and how they are integrated with IE7's
bookmarks (favorites) are very poorly designed, but never the less, it
has tabs. I haven't played with it in over a year, but at that time, a
group of bookmarks could not be opened at the same time. Each tab had
to be opened individually. Like Opera, IE7 feels the need to store
bookmarks in alphabetical order and will not let the user change this
order. At least Opera will open groups of bookmarks even if they do not
open in the order that you want them to open. I wonder how long that it
will be before Microsoft eventually eats Opera and we see "Microsoft
Opera Explorer 1.0" "MOE 1.0"?
