Google Plus has a bar at the top with quick access to all your circles and saved searches.

Until now, the bar had direct links to two top circles. But this has been updated now.

The updated bar provide access to four circles now. the dropdown option is still available.

It’s still a shame that the number is restricted to four considering the service itself is wide enough to handle lots more.

In any case, four is better than two and it is a useful update.
