The new iPad Pro hardware is great and Apple needs to invest in upgrades for iOS to take advantage of it. Here are a few ideas for new features.
No way 9 or 10 are happening any time soon. I am really hopeful for 6, 7, and 8. A resounding “yes, please!” to 3, 4, and 5. With regards to 2, I must be the only person who does not require external file support to get work done on an iPad. I would much rather Apple improve iCloud Drive and third party cloud drive support in the Files app. For the most part, I think these are likely to happen in order from 2-10.
I am looking forward to the future of iOS, whatever it is.
