At the 2014 WWDC conference, Apple's Senior VP of Software Development, Craig Federighi, introduced a couple of new features to the upcoming iOS 8: interactive notifications and frequent contacts.
Now users will be able to deal with incoming notifications directly from the lock screen without having to actually drop into the phone itself. Like a Facebook post or a response to a text.
Also announced was another new iOS tweak involving the double-tap of the Home button. Ordinarily, this brings up a swipe-able list of apps recently opened or used. Now, at the top of the list of apps, will be a bar showing a list of the contacts you most frequently interact with. Tapping on them will open a submenu allowing you to access standard contact interactions like making a voice or Face Time call, or sending a text.
