Hmmm... The new listing still are not showing up in bold for me. Perhaps it's a Firefox issue, my preferred browser. Nope, checked on Explorer, no bold there either. Are you using Chrome? Yes I'm using chrome. Try using the green refresh button on the page next to the search box instead of refreshing via the browser. Though, it seems that to clear the bold entries I have to refresh via the browser.
I second this request - this feature on the old page makes it easy to see what's new. Edit: seems like this may be implemented, I went back to the page and saw some bold listings.
