Here's a handy new under-the-radar feature in iOS 9's Safari browser: the ability to quickly paste an item from your pasteboard, and submit a search via Safari. iOS 9 also allows you to quickly paste a URL and submit the URL.
Both of these features require that a user have text copied to the pasteboard, whether that be a full URL, or general text for performing a search. Of course, this isn't a huge groundbreaking feature, but it can save you seconds, and over time, seconds add up.
