From Macworld:

Mail did get a few tweaks that make wrangling the unwieldiest of inboxes easier than ever. I’ve been using the iOS 10 developer beta on a 12.9-inch iPad Pro for the last couple weeks, and the public beta since its launch. Here are four of my favorite new Mail features. If you’ve found any other changes in the Mail app, share them with us in the comments.

The three-pane view in Mail and Notes is really nice on the larger iPad Pro.
