Secondly, Google+ now has a redesigned notifications menu, which lets you check out content more easily from the menu itself. You can even see how many +1s your posts have received and you can see more content without having to open the post. Google+ Pages have been improved – you can now set up to 50 administrators for a page, the notification flow has been improved, and the aggregated count of users that have engaged with your page are now shown.
Lastly, Google+ Photos has improved: viewing photos in Lightbox is done with a new navigation system, enhanced comment legibility, full-screen mode, a new photo-tagging experience, and a spotlight mode to focus on people in your photos. Users can also edit photographs by adding objects, text and more which can be easily shared with people in your circle. The updates have started rolling out today, but it should take awhile for it to reach everybody.
