@dosnostalgic clear options, obvious ways to cancel completely out of it if you clicked by mistake, dimming the rest of the screen so it took your focus and gave you the power, and a help button that actually tried to help.
No dark patterns, no marketing, no patronising, no "this nameless system icon is preventing your computer from restarting", no "we rebooted automatically for updates, all your work is gone and all your tabs will reload". I miss not arguing with my PC just to get things done.
@dosnostalgic oh, and no "other people might lose work if you restart now!" on my own literal personal computer that nobody else has an account on, nevermind is logged into. It's terrible how much we're forced to just accept our own possessions flat out lying to us on a daily basis.
