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
This is an application of Fitts's law. I saw some paper referencing it to back that kind of margins on destructive actions but I don't remember the title.
Well fitts law doesnt mention anything about asymmetrical spacing anywhere. Infact going by fitts law, the new gnome design is great because the hitboxes are pretty large
That's what the paper was about, the law also applies the in reverse, adding the space protects the user because it makes it harder to click on the hitbox.
