Everything is now run from the toolbar. You can see who is at a website, or who
was recently at a website, view their profile, add comments, send messages, etc.
Moving everything from the sidebar to the toolbar greatly improves the
usefulness of the application. Also, iosurf has moved from a synchronous to an
asynchronous presence system. So, instead of two people having to be at the same
website at the exact same time to see each other, now two users can see each
other if they've both been to the same website within two weeks. This helps in
the visibility of other iosurfers while surfing the web.
3.0 will only be available for firefox for the near future. But it may be
ported to IE when it's feature set is more defined.
