It would be great if we do some hunting of the little tweaks that iOS 10 have for the iPad. I will start. Let us also include non-iPad specific features but will actually work better for Ipad users.
- Three panes for mail and notes. http://9to5mac.com/2016/06/14/ios-10-adds-three
- Swift playground app
- App switcher has a tile for Home screen http://9to5mac.com/2016/06/13/hands-on-ios-10-iphone-and-ipad-tidbits/
- Unlimited Safari Tabs (??)
- Split view for Safari
- Widgets now on spotlight instead of Notification center.
- QuickType - this works well if you are a heavy glass keyboard user.
- iCloud desktop folder http://9to5mac.com/2016/06/13/ios-10-features-developers/
- Side-by-side Mail compose iPad
- Rest & type iPad keyboard
- iCloud Drive Documents folder
