9to5Mac has a long list of features that are coming to iOS 10.3. The biggest change is definitely multiwindow on the iPad, which iOS sorely needs.
There are many changes coming to iPad with iOS 13, including the ability for apps to have multiple windows. Each window will also be able to contain sheets that are initially attached to a portion of the screen, but can be detached with a drag gesture, becoming a card that can be moved around freely, similar to what an open-source project called “PanelKit” could do.
These cards can also be stacked on top of each other, and use a depth effect to indicate which cards are on top and which are on the bottom. Cards can be flung away to dismiss them.
This definitely will make iOS a far more mature and capable operating system, and I can’t wait to try this out on my iPad Pro. All it needs now is proper mouse support, and we got ourselves a proper operating system.
