Google has kicked off this week by initiating the roll-out of a new update for Google+, one that brings some highly-desired features while also improving those already available. First up, Google is adding a slider to every Circle so people can choose how much information from that Circle reaches their main stream. This basically allows users to limit the updates going to the stream, making it more focused on things of greater importance (less spam for everyone). Notifications are also getting a boost thanks to the arrival of 'sneak previews' and the ability to see the +1's and shares received by posts. As for Photos, they can take advantage of a redesigned Lightbox which allows for 'improved navigation, enhanced comment legibility and better overall utility'. Photo tagging has also been improved and is now faster and easier. Last but certainly not least, the brand Pages have been tweaked so they can have up to 50 administrators, all of them updated constantly through the new notification flow. Moreover, Google+ will provide an aggregated count of users that have been +1-ing or adding a brand page o their Circles. All of these goodies are already en route and should be available globally in a matter of days.
