I'am happy to see the new theme coming to serverfault with the ability to watch tag.

One feature that was lacking the old theme was the way the site show a question with a accepted answer, from all the view (the box with the number of answer or the box in the profile's view with your answer). 

It was not like on other SE site (it's a filled green box on other sites like on your printscreen) There on the profile page it's no border, and in the question list it's a black line around in a white background.  (you can see a feedback there for the previous theme change for the profile page; https://meta.serverfault.com/a/8027/256639)

So I'am happy to see a theme more easy to read with those green box, like all other SE's site.
