Yes, animations really influence decisions. Mainly about using the particular piece of software at all (animations are no go for me and a lot of other people).

Yes, animations really influence decisions. Mainly about using the particular piece of software at all (animations are no go for me and a lot of other people). Some folks do not have the luxury to spend hundreds of miliseconds to seconds each time they do some action (and believe me or not, they do A LOT of actions per day). Some people are actually using computers to do stuff as fast as possible so they have fast computers. Having fast computer doesnt automatically mean someone is willing to spend those resources on some eye candy. Stuff moving around actually increases information overload as it adds to state one needs to track (moving object). To some folks this this even causes problems from medical reasons. When it comes to information density, this should actually be up to user as well (lets call it compact mode for example) but at least to me it is not as critical as movements. Best would be being able to set "margin sizes" or something like that. And even that should be completely trivial given that no one should really write fixed-widget-position applications these days (i havent done so in ages, i'm using vertical/horizontal containers and spacers). As should be application color theme as we are/were used to for a loooong time. But I understand that it isn't something Windows users are aware of, since each and every program there forces you to look at completely different interface that behaves in other way and has other ux logic. I do think we can both agree that being able to stop all and every animation (including fading and whatever else in this category) is very important for user inclusion and accessibility. And since (as you said) slowing those down is needed for their development, "disabling" that feature should already be trivial. It just has to be available to user. Otherwise it's just an arrogant negligence and showing over-supremacy by "i know better what you like to look at".
