Twitter updated design

I looked at Twitter from a non-software client, was pleasantly surprised by the interface changes. It is strange that the general public missed this fact by. Apparently, many, like me, use client applications for posting.
So, to the point - what's new for us:

- Immediately noticeable visual changes sidebar.
All three types of statistics - subscribers, subscriptions and ads are aligned horizontally in the upper part. In my opinion, a very good interface.
The user links that were previously at the top of the page moved just below.

- Made changes to the profile design page.
Now you can choose the pre-defined design schemes. The editor of these schemes has also become more convenient. I do not remember whether changes were displayed earlier on the fly, but the ability to adjust colors and observe the changes in real time captures. As for me, a logical addition to the editor and the collection of topics would be the ability to save and share these topics, as was done on one popular blog hosting .

- I also drew attention to the use of Ajax where it really long ago suggested itself. Perhaps this will reduce the number of pages updated, which, in turn, will positively affect the performance of the service.
