They actually changed much earlier than today. You’ll see it’s been talked about for more than a week. You just updated today or didn’t notice until now. If you look through posts you’ll see lots of people asking about it, such as:
- New Page Layout
- How do I get my favorite sites back to the left hand side?
- Move "top searches/home icon bookmarks" back to left side?
And many, many more. It’s sad that people never search and instead just rush to post.
