Hey, Ive been using OS X for a few years now and hanging around these forums and know a lot of the tricks. But there are still probably some nice things Im not using that I would find useful, even ones I know about. Ive kinda known about the web receipts folder for awhile, but didnt actually use it until yesterday. I suspect a lot of people dont even know it exists. What other nice little touches am I missing out on in OS X?
