Only if it counts that I've spent several months using it, and felt constantly irritated by it enough to downgrade (which gave me instant relief).
I just developed a couple of Chrome extensions, and I was irritated to find that the icons aren't decipherable under the new design, since they're shrunk.
It's mostly the tabs that drive me nuts. They waste space and feel clunky, like I'm on a phone. One of my favorite things about Chrome has been its smooth, almost invisible interface.
Guess I'll have to deal with it. I usually do with other changes, but this one has just been rubbing me the wrong way.
