I don't mind it as much.
I heard the width was because it was thought in mobiles and other devices, but I don't really like the two columns thing as much as I like the organization of the timeline in itself. I also feel the opposite way than most people as I feel the information is more at hand and more intuitive than before.
Putting that aside, I am more concerned about all the privacy changes and tagging and photo stuff than everything else. I really dislike not being able to de-tag myself directly in picture and just 'disable the picture to appear in my profile". I am not over that and some applications taht bulk ask you permission to do thing and you cannot decide for either, like ticking each option or something.
You can remove yourself from a tag. I have done this myself a couple of times. And if a pic of you appear on your timeline you can remove the post or hide it
