I have been using iOS 11 for 5 weeks now and I have to tell you that the workflows are better but still no where near where they could/should be.
One example is the Files app. While iCloud files/folders are treated as first class citizens, Dropbox and others, even other local iPad apps, are treated as the bottom of the barrel. Different layout, difficult navigation, distinct / limited workflow options. This is Apple! We expect better.
Another example is PDF workflows. Apple has not put any option to shrink the size of PDFs (a la MacOS Preview). If you print a website using reader mode with dark background, as PDF or actually print out, the system prints the dark background (wtf) not recognizing it’s just a display/dark mode think. The new “create PDF” option has great potential but currently has no pagination option/settings. Any webpage turns into a long, single strip... at least the thumbnail should be the first screen/page, not a strip.
No doubt iOS 11 is a move in the right direction. But we still have ways to go.
