It works very well in my experience and the stuff they’ve added in iPadOS 15 are great quality of life improvements.
Very happy with the developer beta so far, although it has only been a few hours.
Of course not, why would I when the UI sucks so much? "Use it regularly" can also be translated to mean "use it until you memorize the UI gestures that Apple half-assed". I had an easier time memorizing block syntax in Objective-C. It's like vim, only for multitasking on tablets.
Swipe the middle bar to resize the two windows.
I don’t think that should take more than a few minutes for most people to grasp. Honestly it is even simpler than desktop window management.
Most of my apps are not in the dock. There should be an obvious way to initiate multi tasking that includes selecting any app on your iPad - maybe splitting/resizing your single full screen app by dragging from either side of the screen to reveal the app drawer, where one could select an app to fill the space. Of course there would be conflicts with existing gestures. Just thinking out loud here.
edit: Apparently that's how it works in iPadOS 15 [1]:
> Access to all apps
>
> When you enter Split View, the app moves aside to reveal the Home Screen, giving you access to all Home Screen pages and the App Library.
The multi-task gestures - Not much success at all. It shouldn't require a manual and practice to use this.
The only thing I am still trying to grasp is the “shelf” - I see it keeps things like mail compose windows open…but I have been unable to figure out how you are supposed to get back to them later, other than leaving the app and coming back…
For Mail specifically: there's an icon in the lower-right of the sidebar that looks like two squares, one on top of the other- try giving tapping that.
