OS X Hidden Gems was written on January 29, 2010 by Bryan Schuetz. I am writing this at 10:45 PM on the 30th and already 50 people have commented on the article and added tips.
Bryan starts out with:
Have you ever noticed that little dark circle that appears within the close button of a document window in OS X when you have unsaved changes? Yeah, me neither. After years of diligent Mac use, this subtle little element somehow escaped me until now. I guess I remember noticing it at times but never realized it was telling me to save my work. It’s a nice touch and got me wondering about what other subtle elements I might have missed over the years.
I have used Macs since 1985 and OSX since 2001 and never noticed the dot in the close button. I am always amazed on the details Apple has put into its operating system.
There are several more of these “gems” offered in the article and the comments have tons more. See it all at the AppleBlog
