iOS 8 will bring Extensions to your iPhone and iPad. Extensions are essentially miniature versions of apps that can be run inside other apps. For instance, if you have Evernote installed on your iPhone, you could pop up the Evernote Extension when you’re running the Mail app, and save a snippet of that email to your Evernote account.
Clearly this is huge. It’s something that Android and Windows Phone users have enjoyed for a while, but Apple has – typically – taken its time to get it right. In fact, you have probably used Apple’s own “test” Extensions already: Whenever you see the Mail sheet roll down inside another app, or you access the built-in Twitter sharing box, you’re using an Extension.
But what kind of things can Extensions do for us? I’ve been thinking about that, and here’s a wish list of Extensions I’d love to see.
