Remove query parameters - they are rarely used on HN and often contain personal data
Nicer:
faster animations
thick borders replaced with shadow
nicer title that reacts on hover and shows HN news item title
tab graphics improved (text aligned with YC logo onto same baseline, same padding on all sides)
removed forgotten console.log
tab reacts on hover
get a HN discussion with most votes (much better than latest now which is usually duplicate post with 0 points)
indentation → spaces
