What gets me is the new'ish icon, 9 grey dots, I have to click to get to all the various G products that I use. I much prefer the old black "header" where I could easy click between the products
And then there is the address book, hangout/GTalk and G+ linking together, it does my head in that I have people I never email in there. My contacts are my contact, my circles are my circles, I think there is only 5-10 people that I have in both. I enter a name lets say Tony and I get 15 people and only know 2 people called that, yes I follow the others, but that is different. My address book is people who and email and contact regularly not someone who I follow in circles. I know what I mean.
The same goes with farcebook got people whom I am friends with there but don't have in my address book.
anywhoo rant over...
