1. Maybe in 100 years, when we have powerful AI that and reliably identify problematic animation.
Unfortunately, Duolingo ignores this flag for many animations, and more than half of the screens are still animated.
I find the animations Duolingo uses to be obnoxious distractions, and I want them to be actually disabled when I tell it this. I also want this kind of thing to be switchable on a per-app level, so that I have a way to override the (I assume) opinion of the art department or the marketing person that thinks these animations are engaging or fun without having to also disable the non-obnoxious animations my other apps have.
(Mind you, at this point I'm thinking Duolingo has been a lost cause for the last few years; although the courses seem to still be improving, the UX has been getting worse faster).
(eg. to confirm an unconfirmed item, you tap on a coloured bar which then swoops a new pane from the right, shifts it up, zooms the map, and occasionally does a little blink refresh of the map. And you frequently get 4-5 of these a day, each one doing its little UI dance. God help you if you need to convert 10+ mis-identified transport segments to a single bus...)
Turned it on to make phone/ui fast and instant, found out it just doesn’t. Idk what people with vision problems need, but personally I need animations (either fade or motion) to not exceed ~100ms.
A better option is to respect the user, and if your site really can't run without animation, then just show an error stating that...Which shouldn't be a problem considering how many websites refuse to work just because you are using a chromium alternative that is realistically supported but just isnt Chrome itself.
