New GNOME dialog on the right:
Apple’s dialog:
They say GNOME isn’t a copy of macOS but with time it has been getting really close. I don’t think this is a bad thing however they should just admit it and then put some real effort into cloning macOS instead of the crap they’re making right now.
Here’s the thing: Apple’s design you’ll find that they carefully included an extra margin between the “Don’t Save” and “Cancel” buttons. This avoid accidental clicks on the wrong button so that people don’t lose their work when they just want to click “Cancel”.
So much for the GNOME, vision and their expert usability team :P
NeXT is probably the pretty direct ancestor of osx dock. Only Apple turned it from good to bad by moving it to the bottom, where there is no space. And that only got worse as screens became wider, but not taller. And they made it overlap and obscure content and bounce around if you got near it making it extra obnoxious and hard to use.
Other docks existed even before, of course.
