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
When you copy the outcome is almost always going to be worse than the original. Do your own thing and be the person or project you want to be. You don't need to care outside of the project.
This. But 99% of the internet will hate your project for absolutely anything they don't like in it and it will kill the project because distros won't want to use it.
