I forget sometimes when the last time I saved a document I have open, and when I go to close it, it asks, Save/Don't Save/Cancel. I wish it said a time stamp of the last time it was saved so I don't have to save it if I already saved it 5 mins ago and didn't really make any worthy changes. Yes I could just look at the file info in the finder, just seems like a simple thing to add to save some time.
