macOS is using "dot on top of the Close button", to indicate both that there are unsaved changes, and that if you tried to close the window, you would get a prompt asking about unsaved changes.

Simpler, more elegant, better integrated solution, consistent across the whole OS.

"Asterisk in the Title Bar" is a very unrefined solution to the problem.

Asterisk in the title bar lets me see which of my notepads in the taskbar are saved and which aren't.

Not saying it's better, just that your "unrefined solution" might be another man's "feature".

The asterisk (as unsaved indicator) has been there on a lot of Linux programs for a while (the first I remember encountering was GIMP at least a decade ago).

It shows up on the titlebar but more importantly in the window pager/taskbar, which isn't a feature on Mac OS (though to be fair it also doesn't show up on Linux/Windows desktops that are configured to show icons only in the window pager).

Oh god, thanks for the tip! :D I always wondered what that point was sometimes doing there. Somehow the asterisk is easier to understand!
