Chrome Web Store now has a new user interface, which is a lot faster as it uses AJAX to load extension pages. The new UI now has promotional images and larger screenshots, opens extension pages in overlays and makes it easier to install extensions, themes and apps.
Also, infinite scrolling replaces pagination, so you no longer have to click "next".
"Promotional images are your chance to capture users' attention and entice them to learn more. Don't just use a screenshot; your images should primarily communicate the brand," suggests Google in the documentation.
The new interface is only available in Chrome and Chromium, so you can go to https://chrome.google.com/webstore in a different browser to see the old interface.
Here are a couple of screenshots of the new UI:
