I’m guessing you might know already, but just in case you don’t, “reduce motion” in the accessibility settings menu is essential to productivity and sanity.
There needs to be a happy medium. I don't like reduce motion because it amputates many of the spatial arrangement metaphors inherent in the iOS UI.
My biggest problem with authoring shortcuts is that the editor goes out of its way to obliterate context while you're working. Full-screen editors to change a setting lay on top everything else you're working on. Placeholders for variables, which themselves have no actual names. It's a mess.
This does nothing to remove the loooooong animations. Much of the interface still jiggles, wobbles, slides, etc. It just replaces a fraction of those with fade animations that are just as long. It's just a high-latency interface all throughout.
