I left feedback that the sidebars should be collapsable. I also miss seeing the lede under each headline. Even the "Full Coverage" view is missing a preview of article content. Perhaps an issue with fair use?

Regular users will not need that left sidebar to be reminded of what sections they have configured for the page, and it takes up a large amount of screen space. The right sidebar might be useful to more people, but the "In the News" block is just words and phrases pulled from the main content. It seems redundant.

Overall I like the fresh look. Google News is one of the few sites I have been visiting almost every day for well over a decade now!
