Twitter has upgraded its notifications for iPhones and iPads, making them interactive to enable quicker responses. For instance, if you get pinged about a new message while using another app, the improved notification box that pops up allows you to favorite or reply to that tweet without leaving the program you're using. In addition, the latest version of Twitter for iOS adds a button next to your avatar when you compose a tweet, which gives you easy access to drafts you've never gotten the chance to publish. Don't bother unearthing old stolen jokes, though -- Twitter's bound to delete them anyway. You can download the update right now from iTunes; it might not be a major one, but both features are clearly useful if you're always in a hurry.
