This morning when I was checking my Google+ page I was prompted with a popup that said the cover photo is now bigger. They weren’t telling a fib either. I hit the confirmation to update and loaded my preferred cover photo and BAM! The thing is HUGE! Take a look at my screenshots for yourself and then head on over to your profile and check out the update for yourself. Once you do tell me how you like it.
Another notable item is there is a new chat box on the bottom right side of the screen.
