Readdle has pushed out an update to their excellent iPhone and iPad application, Documents, that gives it full integration with your photo library alongside a pretty nifty new drag-and-drop feature. Photos get their own folder, and now right within Documents you can access the photos stored on your iPhone or iPad for viewing, copying, 'open in' and emailing.
The new drag-and-drop system for moving your files around is really slick, and works every bit as well as you might hope. You can use it to move between folders, and even to the sidebar folders such as iCloud and Dropbox. You also now get the opportunity to favorite your files to have the ones you want most easily to hand.
I'm a huge fan of Documents, and I use it for pretty much everything I can on my iPhone and iPad. It's a really slick application that just got a little bit better still. Grab it from the App Store now, and let me know what you think.
