iOS 7 looks set to offer a few nice new features for the built-in Mail app – or at least they’re on offer right now in iOS 7 beta 2.
One of the most notable new features is the ability to mark all messages as read in the Mail app. It’s very easy to do in iOS 7 beta 2. When you’re in the Inbox area of the Mail app you just tap the Edit button at the top right of the left sidebar, then tap ‘Mark All’ down at the bottom right of the sidebar, and then tap ‘Mark as Read’.
In the same way you can also mark all as unread again or flag all.
It’s worth noting that, as with all beta software, features that are currently in the iOS 7 betas may not make it into the final public release. Here’s hoping this one does.
I spotted this new feature via Rob LeFebvre’s post at Cult of Mac.

What about allowing you to look at only unread mail? This is such an aggravation on iPad. I want to be able to easily look at only unread email via iPad.
