Android for example has clearly a bunch of bugs where some stupid slow animations cannot be tured off. Yes even with turning off animations in accessibility and via the developper options.
On iOS, it doesn't seem to be possible to turn any of them off. You can merely "reduce motion". But it still wastes up to second in the worst case.
What about gtk3 or 4. Now there is some crap animation everywhere in gtk applications and I don't know how to turn that off.
Computers are so fast. Most software is already bad enough that it manages to slow down our beautiful hardware. Let's not make it even slower with animations.
Sure have optional animations if that helps newcomers understand better the flow of your application. But make it optional please. Pretty please?
