Hazel is the most useful app on my Mac. Hazel performs all the manual "work" I used to waste hours doing and IMHO a Mac isn't complete without it. I tell it what I want it to do and it does it. For instance I have friends who have literally hundreds of files in their downloads folder. This is not only a mess and looks terrible it makes for a lot of scrolling when trying to find something. Hazel keeps mine clean and organized. When I download a file Hazel sorts it into a folder based on the date. Then Hazel moves any folder that is older than three days to an Archive folder on my backup drive then sorts them into folders based on the month they were created. So I have everything I have ever downloaded on my backup drive sorted into dated folders by month then day yet whenever I open my Downloads folder I only have three folders of the last three days downloads. This is just one of the many tasks Hazel automates for me daily. Pretty much anything you can do in the Finder, Hazel can automate for you. Its like becoming an expert in AppleScript and Automator for a $20 license.
